Rs232 async port 2900

Hi
does anyone remember how do i see if an async port is up on a
CISCO2901/K9 with RS232 async ports(HWIC-16A) ??

Or if you want to avoid to install the javax.comm package, you can access the serial port also without it.
If you're under Windows open a file named "COM1" and you can read or write to the serial port.
for example:
RandomAccessFile serial = new RandomAccessFile("COM1", "rw");I'm using this in a servlet to access a serial I/O device on a Windows XP host.

Trying to configure an Async port on a 1760

is there a difference in the way async ports are configured between 1800 and 1700 RTRs?
i have 3 remote 1800 RTRs that have a dialup backup link via a modem connected to the AUX port.
they work great.
so now i'm tasked with doing the same with a 1760 RTR.
well, thinking that a 1760 SHOULDN'T be that much different than a 1800 i pasted an 1800 config into the 1760.
everything works except the ASYNC port will not accept the " dialer-group 1" cmd.
i'm getting this msg:
"Remove Dialer Profile Configuration first" when i insert the cmd.

You already have a "dialer-group 1" statement under your Dialer1 interface. I think it's telling you that when you try to add a second one under the async interface.

Cable for async port on NM-8AS

Hello,
do you know which cable to use to connect to an async port of an NM-8AS module?
Thank you in advance

I have been looking for this interface for months. Indeed, a source of the connector would be a great help... We are listening...

Constant Failed Attempts from ASYNC ports

Our ACS 4.2 Failed Attempts log is being filled by "noise" on the async (tty0/tty1) from both our routers and switches. We have modems attached to our routers primarily on the console ports, in addition we have the aux port of our router connected to the console port of our LAN switch so we can reverse telnet into the switch. Both router & switch are TACACs enabled. In the user-name field of the ACS log, we get "noise" such as "interface up and down", "Press RETURN to get started", which the authen-failure-code indicates invalid characters or "ACS user unknown" in username field. What would cause this? I know misconfigured modems can cause echo issues but why a switch console port?

Dan/Greg,
This issue occurs when terminal server device (like c2509, c2511 or other) connect to it and which is sending junk to console or aux lines of the Router/Switch.
What may happen wrong with Terminal Server config:
= Incorrect speed for the line (which is connected to console of the router)
= possibly "exec" is running on that line on Terminal Server, thus sending unexpected prompt to the router console/aux.
When you want to allow only an outgoing connection on a line, use the *no**exec* command.The *no exec* command allows you to disable the EXEC process for connections which may attempt to send unsolicited data to the router.
(For example, the control port of a rack of modems attached to an auxiliary port of router.) When certain types of data are sent to a line connection, an EXEC process can start, which makes the line unavailable.
The user will still be able to access the console of the device and be authenticated as well. This puts extra burden on ACS and you may see some latency with legitimate authentications.
Let me know if you have any question.
Regards,
~JG

RS232: Read port delays

I am sending a command from my PC to a unit using RS232 port. Using the serial snooper, I saw that the unit responds with a ACK within 4 msecs everytime. However, my read routine loops for "atleast" 100 msecs before it finds the ACK. I have configured a timeout of 30msecs and I am doing a read only when I see there are non-zero # of bytes at the port. Why is it taking me so much time to see the ACK?
Thanks,
sam

As far as I know, that's incorrect.
When running the flush I/O buffer, you can specify whether or not the contents are to be discarded or not.
The VI is located under "Instrument I/O"-"Visa"-"Advanced"-"interface specific"-"Flush I/O Buffer"
I've translated from the german version, so some names may differ in proper english.
In the help file associated with this VI it states "Maskieren (16) bezeichnet den zu entleerenden Puffer. Beim Entleeren des Empfangspuffers (16) wird der Inhalt verworfen, während beim Entleeren des Ausgangspuffers (32) abgewartet wird, bis der verbleibende Inhalt des Übertragungspuffers an das Gerät gesendet wurde. Verwenden Sie (64), um Die Daten des Empfangspuffers zu verwerfen. Verwenden Sie (128), um alle restlichen Daten des Übertragungspuffers zu verwerfen."
You may realise this as not being English. A rough translation is , set input 16, the transmit buffer is emptied (discarded). Setting 32 will empty the transmit buffer, without discarding. It waits until (forces) the contents of the buffer is transmitted. The further text is not clear to me, stating that (64) discards the receive buffer, whereas (128) discards all other data. I've always assumed this is a typo, and that 128 causes no data loss. Maybe this is my mistake?
Personally, I find this a good way of regaining control of the serial buffer for sending data at least.
Can someone else maybe give the english version of the help file a look and share with us what it says there?

Changing the TCP port on async ports in Cisco router

Hello,
My goal is to replace old terminal servers from a factory environment.
These terminal servers act as a aggregation point of terminal equipment (printers and factory automation).
Software used in this factory writes to these devices using ip-address of the terminal server and TCP-port starting at 10001, where the last number is a port number.
The problem is that in Cisco equipment, I can not find a way to change the tcp port to this 1000x. The only option would be to change the softwares TCP-port to Cisco default 200x, but this is not the solution I am looking for. This is because the switchover should be done when the machines are running, and the time window is to short to make changes in the factory software.
Is there a way to change the logical TCP-port for Cisco routers asyncronous lines (HWIC-16A) to 10001-16?
Marko Tuhkunen

So i figured out that i can use the archive tar /create command:
To copy the entire flash towards TFTP:
archive tar /create tftp://X.X.X.X/flash.tar flash:
Now i will have to insert the new flash and probably format it first towards the correct file systems. Then i will have to use the next archive command:
archive tar /xtract "Here i am unsure of the syntax, i want to be copying and extracting the tar I backed up from the old flash"
After these steps are complete can i just reboot the router with the new flash card, won't there be any issues, since the startup config is on the NVRAM it will load the config properly, and i haven't seen any boot parameters but they shouldn't pose any issues since i'm not changing the flash slot.
Thanks for your assistance

RS232 serial port or 98SE on M105S3041

I need RS232 to communicate with my CNC mill.
I purchased and installed a PCMCIA Serial I/O card but I can't make a serial mouse work. Running XPsp3. Do I have to disable the touchpad? I expected it would work like my M645S4070: plug in a USB mouse, turn off the touchpad, and then the USB mouse is the sole active mouse.
I installed 98SE on the same machine (M105S3041). 512mb RAM. The MS flag banner comes up, and that's as far as it'll go. Anything else I need to do?
Solved!
Go to Solution.

Yes, M645-S4070 is replacement for the M105, as WinXp is no longer supported. I took screenshots on the M105, and sent them to a flash drive to transfer to M645. When I asked to Safely Remove Hardware, I see that the flashdrive is there, and
"CH352 =>PCI SERIAL&&PARALLEL" is also listed.
You say
In Device Manager, double-click the device to open Properties. On the Details tab what does it have for Hardware Ids? Copy the longest line. It looks something like this.
I reply
The longest line is

Help needed by Good Samaritans for info on Drivers for RS232 / USB ports.

Dear all,
I would first like to thank you for taking the time to read my message.
I would like to ask all you proffesional LV developer how difficult it
might be to write the drivers for a bluetooth-RS232(or for a Wireless
LAN ethernet/USB access point) device using LV. Would it be better to
write the drivers in C++?
I have finished the LV Basics 1&2, though we did not learn something helpfull for my case.
Are there any usefull examples i should look at?
The signal transmitted would have a data rate of about 0.5MBbs and the LV program would just display and store the data.
Thanks for your help

Bogiasac
Couple of quick points then I will allow the LV Community to reply to the specifics. From NI's point of view we would recommend that you use the development language that you feel most confident in, so if you are a C++ guru then use C++. Another point, you mention that you attended the LV Basic training classes. I conclude from your comments that you were looking for specific training (while attending did you raise this with instructor at the time?), these training classes are an introduction to the LV environment and set out the ground rules how to best develop a LV application. Our intermediate courses go into greater detail into advanced LV features - though for some this is still not deep enough (future developments in that for LV 8.0 users soon). If you are looking for specific training please contact our Training Co-ordinator in the UK and she will be happy to advice.
On the Bluetooth question, LV has Bluetooth tools built in. These can be found in the Communication palate under Bluetooth (this depends on which version of LV you have, Base or FDS). Please use these VIs to develop you Bluetooth application. There are 9 Bluetooth examples shipped with LV, these can be found by using the “find examples” in the help menu.
Kind regards

RS232 Serial Port - LEDs

Hi,
I have some experience with Java, though not with any direct hardware communication.
Can anyone help me make a simple program which will allow me to control a couple (or more) of LEDs?
Any advice much appreciated.
(I get the impression so far that this is very doable, and that I need CommAPI).
Thanks in advance,
J

presuming the device with the LEDs has a serial connection to your PC, then yes, you'd need to get the Comm API. Then you connect to the device thru it. After that, it's entirely a matter of what the command protocol is that the device expects to receive.

Yes, that helped.

The "gotcha" here was to note that I needed to execute the telnet x.x.x.x zzzz from the terminal server host (x.x.x.x) itself.
Thanks for the assist though - I rated your post accordingly.

Cisco 2811 with NM-16A as Terminal server.

I am currently looking for a Cisco terminal server solution to remotely access through console my private Cisco home lab. I am thinking of buying Cisco 2811 but I struggle to figure out the difference which ASYNC/SYNC MODULE to use. So, my question, is it possible to use NM-16A module with Cisco 2811 or HWIC-16A module must be used? And what is the difference between them?
I found on Cisco website that NM-16A is not supported on Cisco 2811, however some forums stated that it is possible.

If you attach this USB drive to your Mac can it be accessed now?

Can i communicate by the USB port, if my application is set up to communicate with the serial RS232 port???

Hi to all labview users... Please help me with my deadly problem. Last Deadline is on monday next week!.
I got a complete program now, written and tested OK. It communicates with a slave to control a motor. I've set up the program to communicate with the slave by the VISA RS232 Serial Port commuication. and all works fine...
Now the problem is.. that The communication should have been by the USB port instead. So what I have done now, is that i used a USB to RS232 converter. So that the USB Plug is plugged to the PC, and the RS232 end to my SLAVE,
When I send a command to my SLAVE, the SLAVE seems to understand it and it executes the command. But I must read some data at the port after sending my command to the SLAVE, coz, this command ask the SLAVE to start streaming data to me.
All communication to me from the Slave crashes so that i get ( sometimes if I get data ) wrong unknown data i cant understand.
So the big question is: Can i use USB communication although my Application is set up with serial communication if I use a USB to RS232 converter??? ( the Driver for the USB - SERIAL conv. is installed well.)
Baudrate :115200.. parity : none, Data bits: 8, stop bit : 1.
Please help me.....

Hi ZamZam,
Thanks for your detalied description of the problem. However I think the problem is how your USB-RS232 converter is converting the incoming serial command to the USB port. All Labview can see is a "normal" serial port. Do you have some information on the converter? You might also want to contact them to see if they are aware of this issue.
Thanks!

Auto search RS232 port for device

I know I posted this elsewhere, but it was under the wrong board, so I'm posting it again. Hope you understand...
Well my question was concerning how to autoconnect/autosearch a RS232 com port..
Hi
I have attached a device to my RS232 (com) port, to which I send some string commands to control it.
When the user attach the device to his own computer, I want to make it easy for him to connect to it, SO therefore I want to know if it is possible to do a autosearch on the com-ports on the computer (if there is more than 1) to find the connected device?
I can send a string to my device and get a "ready"-response, if this would help.
Best regards

VISA unable to communicate with or see RS232 serial com port

I have a Dell Optiplex GX260 which has recently had Windows XP (Service Pack 2) re-installed on it. National Instruments VISA is unable to communicate with the single RS232 serial com port on the computer. Neither the "VISA Resource Name" control in LabVIEW 8.5 nor the "Measurement and Automation Explorer" can see the serial port. Refreshing the list does not help. "HyperTerminal"is able to both see and communicate with instruments connected to the serial port. In Windows "Device Manager, the serialport appear in the list of hardware without any warnings.
Can anyone please help with suggestions as to how I may be able to get VISA in LabVIEW to 8.5 to see and communicate with the serial port?

First, there is a plethora of messages on this forum and a plethora of information in the NI KnowledgeBase. If someone doesn't make the simple effort to take 5 minutes to perform a search what does that say? The issue being raised has come up, literally, dozens of times. Do you like answering the same question over and over and over and over and over again?
Second, my feelings are not unique. You will find that the irritation of people not bothering to do a simple search is shared by most of the regulars here. Why do you think search engines are available? Just so that ads can be sold?
Third, posting the SAME question in multiple threads is self-defeating. People who try to answer don't know what's already been suggested, and end up wasting their time as well as the poster's time in providing the SAME answer and/or suggestions that were provided in the other thread.
Fourth, simple forum netiquette. In both threads the poster essentially hijacked someone else's thread. This is frowned upon in just about every forum that I've ever seen.
