I can't figure out a way to connect to them with the additional requirement of having to use the network port that they addressed by on the terminal server...in this case, 2001 through 2007.

Kind of thinking out loud here, but what if you make a custom entry in the bb-services file, with the send command containing AT (and whatever else you need), and what you should expect back. CHeck the bb-services man page for details on this, as well as the bb-hosts man page.

I set up a couple of custom network tests using the bb-services file for some proprietary applications, and it seems to work pretty well.

I never tried to do what you want to do, but a custom entry in bb-services would be my first approach. Someone else with much more knowledge and experience might weight in on this as well.

Have you considered "expect"?? It's an extension to Tcl that can spawn a program, such as telnet, and then send commands to it. I have a script that telnets to a given server, answers TACACS prompt if necessary, and logs in, then su's to root - if the password is provided.

You should be able to spawn a telnet command to a specific IP + port number, just as you would on the command line. Send the AT command, wait for the response. If it times out, do one thing, if the response occurs, do another thing. Lather, rinse, repeat.

I haven't yet got into running much stuff via Hobbit, but I've had a lot of success over the last 5 years firing off Big Brother scripts from cron.

*We have a terminal server with 7 fax modems connected to it. A Unix server uses it to fax reports out to various doctor's offices around town. For reasons that we've never been able to figure out, one or more of the modems will occasionally "lock-up", i.e. quit responding to commands. This usually locks the associated serial port on the terminal server as well.*

*And , by the way, I think Hobbit is great! I think it is a big improvement upon Big Brother, although I must admit that we're on the "better than free" license since we are a non-profit, so I haven't seen what Quest may have done with it.*

*Thanks in advance!*
