	I think I know why my serial.device routines failed, but I'm not
sure.  The Hardware manuals have absolutely no examples or description of
how error's are returned, or what happens to your BeginIO.

	After suspecting that read-error's were causing my poor modem program
to flop over and die, I put in a small diagnostic to print what BeginIO()
returned (when I begin the read-request).  For some reason, It came back with:

	2058 (dec) = 00001000-00001010

	However, this doesn't seem to be an error #, as specified by the
serial docs.  Could someone explain to me what it means?  If anybody has 
any examples of serial.device routines that handle read-errors and such 
without freezing up, I would appreciate it.


Aside: Can somebody tell me what the 'memory overlay' bit is on one of the
I/O ports. It has something to do with the WCS, I think.  Also, I could
not find any documentation on the format of the KickStart diskette, does 
anybody have any information on that??

				Thanks A lot,
