Subject: How to send a break?
Date: Sat, 27 May 2006 14:58:44 +0200	[thread overview]
Message-ID: <01b701c6818d$4bcd37b0$1800a8c0@dcccs> (raw)

Hello, list,

I wish to know, how to send a "BREAK" to trigger the sysreq functions on the
serial line, using echo.

I mean like this:

#!/bin/bash
echo "?BREAK?" >/dev/ttyS0
sleep 2
echo "m" >/dev/ttyS0

Thanks,
Janos
