I am having problems with a 3287 printer emulator (xpe3287) from SSI.
The emulator works fine on my bisync lines but when I try to run
it on my sna lines, it will not start up correctly.  All of my host
applications on the mainframe side are genned for a printer on the
last LU.  The last LU on the bisync side is 31 (1F)hex. The last LU
on the sna side is 65 (41)hex. My problem is that 
in /usr/COMM/adm/3270 where I have my configuration files (bsc.pc and
sna.pc) anytime I put in a device id greater than 31 I receive the
error: power on reject - invalid host identification.
When I put in a device ID under 31, I am able to start the emulator
but I cannot print.

I have a couple of questions:

1. Why do I get this error when I do my start3287?
2. When I do a start3287 with a device ID under 31, why will print
not work? 

I have been in contact with the folks on the mainframe side and
they swear that the gens are correct. Can anybody out there tell me what
I am doing wrong???  For background info I am running a DEC 3360 with 2
systech comm boards installed. My software level is 4.52. 

Thanks in advance, Chris
