   Nonsense. PCBoard v14, Opus, QuickBBS, and plenty of others provide
internal ZMODEM support. Terminal programs like Telix also provide internal 
support, so that a BBS program supporting ZMODEM would have to deal with the 
shortcomings (if there are any) in all the terminals out there.

   I think Joe was talking about a C64 and an IEEE-488 drive. That setup 
doesn't support DMA, either, but has no problems running the RS-232 port & 
drives at the same time.
