Have a good look a the source code and you will find that you have a
buffer overrun problem with one of the PMCOM funcitons. A hint is to
look at COMReadBuffer definition, especially the nCount variable!!!1

Give DSCOPE a try to see what the comms is. It supports sniffing on
two com ports so you can see the TX and RX. This is assuming you build
the sniffer cabling correctly:-
	TX => Sniffer Com Port #1 RX
	RX => Sniffer Com port #2 RX
	Signal GND connected to Signal GND on poth COM Port #1 & #2

#1 and #2 could be any com port, but you may have to modify the code
as there are some assumption that may not be correct if you have 4+
ports.
