It's hard to debug this problem remotely, as I've never seen (or
previously heard of) the Percon Falcon before. A 16540 UART is compatible
with an 8250 (unbuffered) UART. Again, all the standard questions and
advice apply. Are you using the right port? How do you know it isn't
COM2? Do we know your PC does not have an interrpt conflict? Are any
TSRs loaded? Does the cable have null-modem wiring when it needs
straight-through, or vice versa? Do the serial interface speeds on both
ends match? Have you told Kermit to use hardware flow control, but no CTS
signal is coming in? What does the MS-DOS Kermit "show comm" command say
after you have given a SET PORT COM1 or COM2 command?
All of these questions apply equally at each end, except I don't know what
the Kermit implentation in your handheld device is. Is it a homegrown
version from the manufacturer? If so, what did the manufacturer test it
against? Did you follow the manufacturer's instructions?
