This is correct I work it like that too with a Worldblazer (V32bis and
others), the line speed is fixed at 19200, and besides the lack of
real bidirectional ports it works fine now!
Make your scripts to put a getty on a port and remove it,
it changes the /etc/ttys does a kill -1 1 and possibly you put
comcontrol/stty commands in it.
But check the /var/spool/uucp/LCK..tty01 and other lockfiles.
So you don't put a getty on a port thats calling in or out at the moment!

set your modem to ATQ1E0 and save it, and when you dial out you start
with sending a ATQ (preferably after the ATZ)

Here is my enable script:
CUT HERE----------------
#!/bin/sh
# sed /etc/ttys file so the com1 modemport is set to on
# but check /var/spool/uucp/LCK..ttyd1 file first
# Before we do anything we remove obsolete LCK files!
/etc/rmuucplocks
if [ -z "$1" ]
then
dev=com1
else
dev=$1
fi
portno=`echo $1 | sed "s/com//"`
if [ ! -f /var/spool/uucp/LCK..ttyd${portno} -a ! -f /var/spool/uucp/LCK..${dev} ]
then
sed "/${dev}/s/off/on/" /etc/ttys >/tmp/x$$
cp /tmp/x$$ /etc/ttys
rm /tmp/x$$
kill -1 1
fi
CUT HERE----------------
And here is my disable script
CUT HERE----------------
#!/bin/sh
# sed /etc/ttys file so com2 is set to off
# and /dev/com2 gets uucp as owner
if [ -z "$1" ]
then
dev="com1"
else
dev=$1
fi
sed "/${dev}/s/on/off/" /etc/ttys >/tmp/x$$
cp /tmp/x$$ /etc/ttys
rm /tmp/x$$
/usr/sbin/chown uucp /dev/${dev}
kill -1 1
#/usr/local/bin/comcontrol /dev/${dev} bidir
CUT HERE----------------
And now the rmuucplocks script
CUT HERE----------------
#!/bin/sh
#remove old uucp locks
# get the pid out and look in the ps list if
# the process is gone, then remove the lock
for i in /var/spool/uucp/LCK..*
do
pid=`cat $i|tr -d " "`
x=`ps ax | awk '{print $1}' | grep "^${pid}\$"`
if [ -z "${x}" ]
then
rm -f $i
fi
done
CUT HERE----------------
Hope this wil help!
