I just bought an internal TB+ and I'm getting terrible throughput with
it on incoming data - between 200 and 300 bytes/sec. when connected
is FAST mode.  I know it connects in fast modem because I have had
sites use uutry to test the connection.  The only time I get goot
throughput is when data is outgoing.  So, since I've heard about
switching the 8250 with a 16550AFN, I thought I'd try it.  Where can
I get one?  How much do they run (average)?  I'm running AT+T Unix
SysV/386 and would like to get a driver that would turn on the buffer
(someone mentioned a JJM driver?).  Could someone help me out with this and
let me know where I can get such a beast?  One last question - is there 
any difference between a 16550A and a 16550AFN?  Thanx in advance for all
the help.
