It's widely known that 386/ix (2.0.2, new X5 driver in case you care) async
throughput stinks, particularly if your async port has an unbuffered 8250
UART.  So I got a 16550A, unsoldered the 8250 from my internal Telebit
modem, soldered in a socket, and stuck in the 16550A.  I can send stuff to
other sites at 1200-1400 cps, which is what I hoped for.  Inbound news is
still a lousy 500 cps.  What gives?  The modem is set up as ttyd1, with tty00
being a mouse that I don't use much.  That wouldn't be a problem, would it?
