I've reciently been playing with printers and have managed to hook up
my 11 year old Apple ImageWriter, configure the printcap entry, and
insert a filter that uses ghostscript to render postscript to the
Imagewriter.  I'm even shairing the printer via SAMBA and can print to
it from my Windows system.  This is all very cool.

But there is ONE PROBLEM.  I can't get flow control to work.
Characters get lost and the print job get messed up.

The printcap man page mentions using ms=<stty type capabilities>,
which I tried.  The Handbook mentions using fs@0x1123 to set bits,
which I've also tried.  And I've tried both hardware flow control and
software flow control to no effect.  I suspect that whatever
configures the serial port is failing to set the flow control options.

When I had a similar problem while configuring this printer for
Windows I simply when to the Advanced port cofig dialog and selected
"Hardware Flow Control" and the problem was solved.  

So, Anyone solved this problem and know what to do?
