Greetings, Netlanders!!
Could someone out there please advise me on the problem I am having?
Problem Statement:
------------------
I have an ATLAS 2400/1200/300 baud modem connected to my AT class
machine. I am using Procomm 2.3 to communicate other systems. I
can't get Procomm to correctly execute the Hang-up command (ALT-H).
When I issue it, the message "Disconnecting" appears, followed
shortly by "Hangup failed". The link remains intact.
When I had an Avatex 1200 baud modem, Procomm would correctly execute
the Hang-up command (ALT-H). Now, ordinarily, I would jump to the
conclusion that the fault is in the modem. However, it claims to be
compatible with the Hayes command set. Curiosity got the better of me
so I checked Procomm's Hangup string with what the modem's manual claims
is the correct incantation (or at least, the right components).
Unfortunately, I still can't get the beastie boy to pay attention and
hang up the phone.
I *AM* able to break the connection by exiting (ALT-X) Procomm, but I
would prefer the clean, prescribed mechanism (especially if I end up
using a command file to do this automatically). Can anyone out there
help?
Questions:
1. Do I have a timing problem (1200 baud vs. 2400 baud)? I.E.,
do I need more characters in the command to the modem? Does
anyone know the right incantation? Any Atlas modem users out there?
2. Does this version of Procomm (it's older, I think) have a bug?
3. Is this modem *NOT* truly "Hayes Compatible"?
Your help is appreciated.
George

Well, the answer is simple. When all else fails, RTM. Of course, I had to go looking through the archived files to realize that I HAD a manual. Anyway, the ProComm (TM) manual talked about ALT-H (Hangup) in some detail (pp 14, 41, 47). It seems that the Carrier Detect Mask, a value that ProComm (TM) relies upon for determining the success of Hangups, must be set to the proper number. I still don't really know what the mask stands for; the Modem's manual was of no help on the matter. According to the ProComm (TM) manual, most modems default to either 32 or 128. My CD mask was set to 32. When I set it to 128, the problem went away. Hangup (ALT-H) now works as advertised. Oh, a point of clarification. ALT-H *WAS* breaking the connection, but it was *NOT* reporting that fact. So, if you have an internal modem, you don't really know the state of things. If you have a messy desk, you're in the same boat (can't see the lights). Just for the record, ProComm (TM) is a trademark of PIL Software Systems. I have no connection with PIL Software Systems. My thanks to those who responded. I hope this information is of general value to the net. George =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= George J.
