- I use the original cable which was shipped with the switch
- I have uses 3 differenet PCs
- I can use telnet and ssh, but I need the serial also.

Answer 1

It sounds like your getting to the switch just fine.  The issue seems to be you don't have the password to get into it.
If that is the case, you can reset the password and login to the switch using the following steps.
The password will be admin and the username is admin.
Q. How do I recover the password  of my switch?
A.If you do not know or have  forgotten your password to get into the switch's configuration  interface, you may try running the Password Recovery.  This is a solution which allows the user login to the switch using its  default username ("admin").

Step 1:
Connect  to the console port using terminal emulation parameters (typically 38400,  8, 0, 1, None).
Step  2:
Reboot switch by unplugging the power.
Step  3:
Hold down Ctrl U while rebooting  to display Menu.
Step 4:
Select [D]  Delete file.
Step 5:
Type  "startup-config" (be sure that this is the ONLY file that you delete -  if you delete other files, you will have to reload the firmware)
Step  6:
Now, you have erased the configuration file and  you should be able to reboot and login with the default username and  password.
