Transparant printers and XON/XOFF-handshaking

Hi !

I've got a problem with transparent printers - perhaps anybody can help me ?

We're using an Altos 386 Series 600 with Wyse 120 terminals using a VT 100-
emulation and some printers. The Wyse terminals have a parallel IBM-compatible
printer port and two printers are connected to terminals as transparent
printers (one over modem, one direct because at the moment there aren't
enough ports but we have to upgrade).
The transparent printers work fine although the terminals are blocked while
printing but I think that there's no way to solve this and this is not my
Normally the terminals use XON/XOFF to tell the computer to send data and this
works without problems, too - if a user is logged in.
If a getty process runs on the terminal the line is in raw mode and the
XON/XOFF doesn't work. The result is that characters get lost.
I have tried to set the parameters manual by using xtty, a command equal to
stty but you can use it on other lines than your own, but getty resets them.
I have tried to change /etc/gettydefs, with no effect.
I have tried to set this options with setmode, without effect.
I could set the parameters in the printer spooler script for this printer,
but unfortunately the application we use doesn't work with it - it directly
accesses the device.

Perhaps anybody can help me with this ? The Altos vendor can't help us, they
gave me the hint with setmode but it doesn't work and now they have no other
idea :-((((

Many thanks for any useful answers !!!

Sorry for mistakes, but I'm still improving my English !

1. Serial printer, XON/XOFF flow control, anyone?

I am looking for anyone who is using a serial printer with XON/XOFF flow
control. We seem to be a distinct minority. I am wondering if it works
for anyone!

At one time I had mine working (even wrote a section in the HOWTO for
it). Since then, things have changed. While I can cat files to the port
directly with no problems, lpd seems unable to do the flow control
and I lose characters and eventually get garbage printouts. I got the
newest lpd that I could find, and upgraded to a current kernel which
was supposed to fix some XON/XOFF flow control problems (1.1.44 at the

Unfortunately I print very rarely so I have no idea when things actually
stopped working. I have libc 4.5.26 and kernel 1.1.44, and the lpd was
from the NetKit-B package I believe (newest version as of about Aug. 12).

3. lpd and Xon/Xoff possible? for serial printer.
