Hello there!
I have a hipath pbx, and i connect to it via a serial cable (V.24). There is no network card.
The last days when doing the same procedure as always via HiPath Manager E software i get a "Logon rejected" message everytime.
Normally i was using "31994/31994" combo but it doesnt work anymore.
Going through the last lastload.kds i also found two more usernames 633423 and 18140815. I tried both combos 18140815/18140815 and 633423/633423 without success.

I checked the cable using a polymeter and he pinouts seem fine. The siemens technician does not deal with these types of pbx's anymore and he doesn't know any backboor password ( as i read in this forum that there is one).

I could try a reset and load the last backup i have, but i fear that if the mainboard holding the COM port is failing, then i will not be able to do a restore.

Is there any way i can check if the com port is fully functional?
Or is there anyone knowing how to access the system via a backdoor and maybe reset the 31994 password?

Best regards.
 
You need to enter the programming mode via the system telephone to check passwords. Then you will know for sure that the COM is working or not.
