We have problems to connect the serial printer MT490 to our VAX 11/750,
which runs 4.3BSD Unix.

The printer works until it gets an input buffer overflow. We know that
it sends xoff about 500 times until the overflow happens. The VAX ignores 
that sending more and more data.

This is the entry in our printcap file:

lpw|pbinfow|vaxw line printer MT490:\
	:lp=/dev/ttyA2:br#9600:fs#06360:xs#40:tr=\f:pl#72:pw#80:\
	:lf=/usr/adm/lpd-errs:sd=/usr/spool/lpd-pbinfow:

We tested the same serial port with a VT100 terminal and an entry in
/etc/ttys. It works.

Please tell us, if you know how to solve the problem.
