The failure with the SMC chip is a result of interaction between software
and hardware, and is somewhat variable from chip to chip. I'm not aware of
a definitive test that is available, but you can probably create one on a
PC by
using a second (non-smc) port and sending characters from that port to the
smc chip while enabling and disabling the FIFO on the SMC port.

Yet another fix is a 700 byte TSR I wrote for DOS users - it's available
via FTP at ftp.mcs.net/mcsnet.users/brooklyn, file name PRTFIX.EXE. Some
users also use it for Windows by loading it before running Windows - it
seems to help in situations where the replacement drivers do not.

Hope this helps!
