Capturing TTY ports

[Nalyd]

I'm currently using Minicom to capture data on the TTY port, and logging the whole session. I'd like to run this as a cron tab, but once I've started Minicom with cron, I don't know how to stop it (short from killing it, which will destroy the capture file).

Is there a way to directly read the TTY port without Minicom? The data I'm trying to capture runs every hour for about 2 minutes.

Thanks, Nalyd.
