Request To Send.  See the EIA232 specifications.  Maybe there's something
in /etc/inittab which should be commented out.  Hree are the entries in
one of the distributions (Slackware I think):

#----------------------------------------------------------------------
# Local serial lines:

#s2:12345:respawn:/sbin/agetty -L ttyS1 9600 vt100

# Dialup lines:

That won't find the inittab entry. :)
