Probably no help for the Xerox 820 but I have just been through the
exercise to get Generic CP/M 2.2 Kermit to work with Grant Searle's 9 chip
Z80 machine (
http://searle.hostei.com/grant/cpm/index.html).
It was an interesting experience. After some digging to understand what
Generic Kermit requires (written up here
http://www.quicktrip.co.nz/jaqblog/home/69-z80part4) and working with Grant
on some BIOS changes to fully support IOBYTE, Kermit is working really well.
At 115200 baud and with command line Kermit running on my Macbook, bulk
file transfers are a breeze.

Just a quick update to let you guys know I finally got
Kermit80 up
and running. Found
MLOAD.COM and got it transferred over and used it
to link the kermit hex file and the Xerox 820 overlay. Played with it
a bit last night and hooked an old Hayes 14400 modem up to the comm
port and although I can set the command string(s) for the modem, it
doesn't hand control back to the terminal after it connects (was trying
to get it to connect to an old 80286 that has my TRI-BBS software on it)
I'll probably have to stick with transferring stuff back and forth with
Tera-term or something similar. There's kind of a grey area with Kermit
on just how much control it has over the machine's comm port (varies from
one machine to another), so maybe I'm trying to run data through it
faster than what the port will allow.
I need to get with Chuck Guzis at some point and get a license for 22disk,
just not right this minute, until I get this months bills caught up. :P
Thank you Chuck, and everyone else for your help.
