The beta-test release of the CP/M 3.0 BIOS necessary to support an RS232 device
has been available for some time now via such services as Compuserve, Genie,
Delphi, etc.  I don't know any other way to get it except, of course, via
U.S Mail from someone who has it.  It still has a few glitches, but works quite
well with a modem and comes with IMP, a CP/M modem program that is equally at
home with 300 or 1200 baud, auto-dial or manual-dial modems, and does XMODEM
transfers very nicely.  The BIOS slows down the Z80 anywhere from 6 to 90%, so
it's best to crank down the baud rate when you're not using the RS232 port, 
cause they poll it *all* the time, not just when it's being used.  Give
Commodore another few months and I'm sure they'll tell you it will only be a
few months more now!
