Re: OpenNETCF Serial not working in my WinCE 5.0 device

A framing error indicates that the parity or the byte size is wrong,
generally. You might set a breakpoint at the point where you're about to
send the data and check the current settings for the port you're sending it
on and make sure they match the external device. It sounds to me like
you've set the parameters, or one of them, to the wrong instance of the
RS232 class or something like that (copy/paste error, maybe).
