>Version 1.1 beta still doesn't work whith my application ! 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 >What happens if a interrupt can't be handled in protected mode ? (eg using >high speed+ function in RM) 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.
