Rumor has it that Tony Duell may have mentioned these words:
Is one serial port enough? If so, might as well use a
8250-like thing and
a MAX232 (or LT1130-series) buffer.
Heck, at Jameco you can get the 16550's for $6.95USD qty 1... knock off a
buck for qty 10+, and you get the 16-byte FIFO's for better thruput...
Thru Digi-Key or Mouser, I think you can get the 16650's (32-byte buffer,
isn't that the difference??) but I have no clue for the price.
I think it's blackhawk technology is using the 16550's for a new RS232 card
for the CoCo that can achieve 115200 reliably... and it has a daughtercard
for a second serial port to boot. IIRC, they were $69.95 each.
