Then does the device sending data support XON/XOFF? XON/XOFF seems to
work better with PCs but I'm not clear on why. Note that with a PC, the
floppy drive MUST NOT BE USED when the serial interface is in use. The
floppy will cause dropped characters (the PC implementation of the
floppy interface is sinful). This is a long shot but consider using
Linux for data logging. It has much lower interrupt latency in general
than does Windows. Dropping back to DOS, any version through 6.x, gives
low interrupt latency as long as the floppy is not used. Finally, set
baud rates as low as possible and run no other applications in Windows -
don't even run a screen saver.
