Thanks for the input!

Well the things here are very interesting:
I'm unable to connect to the vm from cosession (tried all settings) but was successful connecting using hyperterm in vt100 mode. the autoexec.bat is set to the speed of 9600bps which is strange and there is no cossession host software installed (it uses dos's mode.com). Moreover, the directories on the drive are
ACD <DIR> 08-05-2002 11:58a
BICOM <DIR> 08-05-2002 11:58a
DEFAULTS <DIR> 08-05-2002 11:58a
DOS <DIR> 08-05-2002 11:58a
PCM <DIR> 08-05-2002 11:58a
UTILITY <DIR> 08-05-2002 11:58a

Also, when I try to start acd.exe, it gives me "BLF" errors for every channel.

There is some programming exist on the ksu and on the vm.
Coud I reset the ksu and vm to the defaults and reprogram from the scratch?
What is the procedure?
Thanks again!
