Not true. I have written 2 application in TurboC 2.0 that talk to COM1 using
Int 14 and they run at 4800 BAUD. I haven't seen any problems with character
loss. Had some problem with applications at 9600, but nothing below that.

This was with ATT PC 6300 BTW, using standard serial ports and ports on
Intel Above board cards.
