Accessing modem registers with serial interface

Question

Is it possible to access the registers of a modem (which is under test)
with labVIEW, the modem is connected to my PC with a serial (RS232) interface,
I tried using the serial commmunication VIs but they did not work. I want to send read (RD) and write (WR)commands to the modem in a similar fashion to the way I use hyperterminal.
Ben suggested using the AT commands but I dont knowhow to do this from labVIEW, what I hope to do is download scripts, which are just register accesses, and then just view the status of some registers
Any ideas?

Answer 1

Dennis,
I do not have the exact commands that I will be using yet but the communication will be very similar(but with more RD and WR commands)to the attached hyperterminal session, this simple session works fine with the modem. I want to do this in LabVIEW, with the same settings.
Ive tried to use the "LabVIEW <-> Serial.vi" in the get examples section, but it was throwing out strange responses(even when I appended the commmand with the carriage return) it would return "r f2" or something for a read command and "w f2f" for a write command and then it would give the right reading on the next line.
Also just wondering is there a way to automatically append the command with the carriage return character?
regards,
Kevin Staunton
