I have a printer which has a built in buffer, and signals ready/busy on
RS232 pin 19 when the buffer near's full.  I wish to drive it from a MicroVAX
with a DHQ, running ULTRIX v4.0.

Is there an option to lpd that will configure it to only send data when
pin 19 is ready?  I've tried using a "blue box" to jump pin 19 to DCD on
the host.


The printer supposedly sends XON/XOFF as well, but this is not being respected
by lpd.  Is there an lpd option for this?


If this isn't possible with a default lpd filter, does anyone have one that
will do this?


I'm trying to use it with GhostScript, but I start losing data when the
internal
buffer fills up and I lose synchronization with the pin-graphics commands.
