Apple LaserWriter & AT&T 386 V3.2 problem

[Chris Moran]

I have a problem for which I expected to see a solution in
the 'Frequently asked questions section' - but it wasn't there.

I am attempting to run an Apple LaserWriter IINT off a serial
line on a 386 running AT&T 386UNIX V3.2.

When I set up the lp spooler option for the laserwriter the
postscript data are sent (the little green light flashes merrily away)
but the printer produces nothing.

I then decided to ignore the OS and write a bit of code that
sets the port characteristics and then forks.  The child sends
characters to the printer and the parent reads any
feedback from the printer, i.e., error messages and EOT.
When I use this code to write to the printer I get the same
response as using lp and all characters returned from the 
printer are zero.
I have used similar code under BSD4.3 and Microport 286
and it seems to work O.K.

I have just been reading that other people have had some difficulty 
with modems .  Should I be setting some getty or uugetty or
some other process running?

I should appreciate either some hints as to which sections of the 
manual I have not read closely enough
OR
Could somebody give me a concise set of instructions for this
(apparently trivial) task.

Thanks in advance. I would prefer replies by email, please.
