Default modem problem

I can use cu to connect to my multitech modem and get OK from it. For
the same setup, using kermit, both set line and set baud are successful.
After connect command, no at command is echoed and the only choice for
me is to go back to the c-kermit prompt. Please help.

Default Re: modem problem

Do you mean that after you connect to the remote machine (after connect
command?) that you don't get another AT prompt? If so, then you shouldn't be
getting the modem command interpreter because you are then talking to the
remote host.

If you are entering "+++" and not getting the AT prompt, then that's another
issue.

Probably the modem is configured not to echo.

C-Kermit> set line /dev/cua0p0 ; or whatever
C-Kermit> set speed 57600 ; or whatever
C-Kermit> set flow rts/cts
C-Kermit> set carrier-watch off ; so you can CONNECT without carrier
C-Kermit> connect

Now type:

ATE1Q0V1

and then press the Return or Enter key. From that point on it should
echo and show results.

If not, watch the modem lights to see if it's receiving characters.

Or maybe you're using the wrong device -- you should use cuanpm devices
with modems, not the ttynpm or other names for the same devices.

By the way, if all you want to do is make call, you don't have to type
AT commands at the modem. Kermit has a DIAL command for that:

C-Kermit> set modem type multitech
C-Kermit> set line /dev/tty0p0 ; or whatever
C-Kermit> set speed 57600 ; or whatever
C-Kermit> set dial display on ; if you want to watch what happens
C-Kermit> dial 7654321

For more information, type "help dial" and "help set dial" at the
C-Kermit prompt.
