I don't know anything about the BIOS implementations on the Z80 cards, but I
use the exact same executable of Kermit on a variety of CP/M hardware. The
common feature of these machines is that they all support the I/O
byte. I've used
this executable on the Televideo 802 (pretty much a normal CP/M type of
setup), the Epson PX-8 (not even close to the hardware of the 802) and the
DECmate II (where the Z80 can't even touch the UART! It has to give messages
to the PDP-8 to do all of the work), but because all of these systems implement
the IOBYTE all of them can use the same executable of Kermit.
