As have been pointed out by many, the COMMs handling in Windows 3 in 386
Enhanced mode is simply awful! Character loss will occur at high speeds on
both high speed DX's and 16MHz SX's.

The 8250/16440 compatible chip NS 16550, mainly a chip suited for UNIX, XENIX
or other non-realtime OS's, saves the day for Windows 3 users. I've had the
chips around for a while, but only last week did I fetch the soldering iron
and did some surgery to an old RS card.

Installing a serial driver in CONFIG.SYS patched up for the 550 FIFO support,
and.... whiz bang! 38400 baud without problems on a 20MHz SX.

If only the terminal emulators could speed up a bit.... DynaComm barely keeps
up with 4800 baud...... Anybody seen a fast Windows terminal emulator ????
