Hi everybody!,
         the latest on the Ultrix printer problem.

    I set up the fs parameter in the printcap file for 8-bit data and it is now
printing in English text ( before it was printing in the DEC Multinational set)
but it isn't handshaking i.e. I get buffer overflow on the printer when I send
a file that's bigger than the buffer on the LG01 printer.
    I have looked at the data on the serial line with a protocol analyser and
can see that the printer is trying to send X-on and X-off but seems to be
setting the top two bits, which Ultrix isn't recognising. I have tried the fs
parity options ( odd , even , no etc. ) to no avail, and the printer doesn't
seem to be able to receive data in one format and send in another.
    If somebody has an LG01 on an ULTRIX system or has seen somethimg like
this before, please will you mail me some advice or help.

                        Thanks
