Has anyone had any problems with hooking up and using a HPlaserjet
to a Sun3/50??  I connected a nul modem cable to serial port A on
our 3/50 and before I could get the printcap entry changed, the
machine rebooted twice with messages similer to the following:

panic: parity error
(other stuff deleted)
MEMORY ERROR! status D2, DVMA-BIT 1, Context 0
Vaddr: FFDE68C, Paddr:003EA68C, Type 0 at FFFF9630

I hadn't even changed the menu on the HP to serial yet.  I finally
got the printcap changed and the HP menu changed.  It halted about
4 more times within the next 20 minutes all during printing or
attempts to print.  We are running a LaserWriter off the other port
with no problem.  Since I disconnected the cable to the HP we have had
no problem.  Has anyone had a similer experience or have any insight
to the problem. 
	Also, are there better filters then the lzcat, hpf stuff floating
around???
