hello,
i have wired myself a nullmodemcable to connect a small machine to my 
centos-ltsp-and-so-on-server. using agetty i can login fine, just a few 
garbage chars here and there but working is ok. now this isnt what i wanted, 
so i disabled agetty, made a line in syslog.conf like
*.* /dev/ttyS0
and made the system produce a lockfile after syslog is started to lock that 
serial port. now data reaches my minicom using terminal emulator, but its 
garbage, looking like this:
...x.x.x@..x.x. 
and so on. if i do
echo "somechar" > /dev/ttyS0
its the same garbage. im sure this is a quite simple thing, but i dont get it 
to work. do i need another terminal prog if i try to send plaintext with 
syslog (as it seems to me clueless as i am). do i need to manipulate syslog 
output somehow? i tried to fiddle around with setserial but the port should 
work, as they to with agetty. i hope someone on this list has experience with 
this, doenst seem to be too popular.
    

You need to set the speed and parity to match at both ends on the
serial port. Agetty probably cycled through some speeds to match up
or had a config file.  Stty will show/change the settings but I think
they revert to defaults on the last close.
