Serial communication

Hi,
I need to establish an automatic communication on a serial line with a
gsm. I'm wondering whether it is possible to issue some commands in a
script fashion so that I have not to put commands by hand every time I
need to send a SMS, for instance. I'd like not to spend too much time
making a C program.
What I need it is a method to feed a serial terminal (like cu or
minicom) with scripted command, skipping the interactive mode.

Thanks

I would and do use c-kermit for this. Do a web search for "c-kermit".

If you need to wait for a response from the device, you could use chat
or expect.

What about minicom?

good luck, Holger

Using expect worked very well (I was able to collect and process data
easily scripting in tcl language).

Thanks a lot
