We've got a Sun 3/260 running SunOS 3.5.  On our Sun, I have installed a
data communications processor board (DCP), and required software.  We're
trying to run the Sunlink X.25 package on that board over a telenet
connection using one of the board's RS-232 ports (dcpa1).  All the
required software and kernel mods have been installed/done.  Here's my
problem:

I issue a "dcpattach dcpa1" : everything looks ok I issue   "dclpoad
dcpmon.image" : and get the message on the console - "dcpa: initialized,
max vrtx addr=6b50" So far, everything looks okay, right?  I then proceed
to start up the X.25 link by issuing the follwing commands: x25start dcpa1
9600 system responds: speed=9600, loopback=no, nrzi=no, txc=txc, rxc=rxc I
then issue the command "x25config" here's where the problems start. I get
a message on the console about every 5 seconds as follows:

	dcpa: zss1: xmit hung, donebits=0
	dcpa: dma count = 1, zd_xact=f780:3000, rr0=38
	dcpa: zss1: xmit hung, donebits=0
	dcpa: dma count = 1, zd_xact=fc00:3000, rr0=38
	dcpa: zss1: xmit hung, donebits=0
	dcpa: dma count = 1, zd_xact=ff00:3000, rr0=38
	dcpa: zss1: xmit hung, donebits=0
	dcpa: dma count = 1, zd_xact=ff80:3000, rr0=38
	dcpa: zss1: xmit hung, donebits=0
	dcpa: dma count = 1, zd_xact=fd00:3000, rr0=38
	dcpa: zss1: xmit hung, donebits=0
	dcpa: dma count = 1, zd_xact=400:3000, rr0=38
			"	"
			    .

This continues until I issue the dcpreset command.  The real strange thing
about this, is that I was able to get the thing working about a month ago
by running dcpdiag before issuing the x25start and x25config commands.  At
that time, I was able to pad to various computers via the X.25 circuit.
If anyone out there can make suggestions as to what might be wrong with my
setup, I will greatly appreciate it.
