Yep - that's pretty much the same behaviour as I get - thought it might be Cygwin but maybe it's a Kannel problem.
I'm not 100% convinced that the auto speed detect and port opening code on Kannel in AT2 is as robust as I'd like it to be as sometimes it fails and inifite loops things like the below. When this happensI have to kill the processes, go into Hyperterm (or equivalent), clear the serial ports with a few 'AT' returns and then restart Kannel. Kannel seems to leave the modem in some sort of semi-blocked/locked state which means it needs flushing, and the startup code isn't able to do this itself (even though it has quite a few 'AT' returns in it to try and achieve this). Any serial port gurus out there think of what might cause this?
