Hi,
We use C-Kermit v6 on SCO to dial out, and have recently replaced our modems
with a new batch. Since doing this, our usual dial command of SET MODEM TYPE
HAYES-HIGH-SPEED no longer works - fails to initialise modem. These modems are
based, apparantly, on the same Rockwell chipset.
Hence we moved onto Kermit v7, and use SET MODEM TYPE GENERIC-HIGH-SPEED, which
initialises the new modems fine. None of the other SET MODEM TYPE options seem
to work, including the Rockwell ones.
Now we have some really wierd issues though. For example a system was built in
location A, and tested with a modem which dials the number without problem using
the DIAL nnnnnnnnnn command.
Moved this system to location B, and you can hear the modem dial about half the
number and then give up making some v strange noises. Trying a different phone
line gives similar results. If I CONNECT and type ATDTnnnnnnnn instead of using
the DIAL command, it dials and connects fine. Hence it seems the modem and phone
line are all OK. All phone lines are wonderful British Telecom ones. Workaround:
use DIAL nnnnn; DIAL nnnnn ie. split the dialling in two seems to work.
Another system, similarly configured, won't even dial at all, or go off hook,
despite being the same as the above. However if you in kermit CONNECT and
ATDTnnnnnnnn it dials with no problem. Workaround: After much messing about,
changing the DIAL PACING seems to help a lot.
So this seems to be some sort of joint problem with the phone lines, modem and
the way kermit initialises the modem. Can anyone throw any light on how I should
be setting Kermit up properly, or is this a known issue with certain types of
phone line, can I ask BT to change anything, etc?
thanks for the advice
-Rob
