unable to key in "at" after connected to modem via kermit

N4000 server
HPUX 11.11
kermit version: C-Kermit 7.0.197

Hi, I'm running kermit on serveral servers without a problem. However I'm experiencing an issue on one of my HPUX11.11 servers. I can connect to kermit without a problem. Then when I attempt to key "at" it blows up. Most interesting is, after I make the connect, I'm okay, after I key in "a", I'm okay, but immediately when I key in the "t", I get bounced. I don't even get a chance to hit the enter key. Here is my output:

@osihpn04::super_ /etc/uucp> kermit -l /dev/telnet/irn4_mod1
Executing /usr/share/lib/kermit/ckermit.ini for UNIX...

Re: unable to key in "at" after connected to modem via kermit

Hi Kirk,

The first thing to check is whether there are any differences between this server and the others. Are you running the same version of Kermit, are the modems the same, are the cables the same, are the modems configured the same?

Could you show an ll and a lssf of the device file you are using on this system, and on a working system.

regards,

Darren.

Re: unable to key in "at" after connected to modem via kermit

Hi,
other generic check:

- check stty settings, maybe there is some difference, and the keying of at execute something different

- check arpa and stream patch, if they are the same as a working server. i know it's quite generic, but there is the chance that the stream of bytes is interpreted as the escape sequence, due to some mystical reason


HTH,

Re: unable to key in "at" after connected to modem via kermit

Thanks for the responses.

I was poking around and noticed the following:

There were two different file sizes on the following file between working system A and broken system B:

/usr/share/lib/kermit/ckermit.ini

I noticed on working system A the following was in the file ckermit.ini:

set carrier-watch off ; fix for c-kermit 7.x - timn 071602

Well I copied kermit.ini from system A to system B and it worked. But to be completely honest, I don't know why it works with this setting (besides maybe the modem not liking set carrier-watch set to on). I really haven't had time to investigate.

Re: unable to key in "at" after connected to modem via kermit

The modem only signals carrier detect when it has either dialed or been dialed up to another modem and they have completed their handshake. At that time carrier detect is asserted. The old kermit file didn't ignore the state of the CD line. With the new parameter it ignores the CD line and allows a connection that can only be terminated by the user with a quit.
If it has wheels or a skirt, you can't afford it.
