Issuing GSM commands in the ASU environment?

[Ken Restivo]

I need to get to /dev/ttySAC0 in order to find the hardware revision, and also to issue my caller-ID-suppression command.

On the ASU software, lsof reports that /dev/ttySAC0 is in use by the "qpe" process.

How can I shut that down so that it releases the lock on the tty?

If I just killall qpe, it leaves the port open, apparently, and cu won't open it after that.#
