Because the parallel adapter in the PC and AT is UNI-Directional - it can
send but it can not receive data.  Also, a PC (not AT) can hardly keep a 9600
baud connection going full tilt - 19.2K on a PC is a pipe dream.  Sure, I can
do it in BURSTS, but what happens when I need to get the next part of the
file to transfer?  Or when the clock interrupt goes off?  or when sidekick
wants a few clock cycles?...
Brooklyn Bridge is Great - but not really a replacement for a smart network
card...
