i am making the application for an ipaq (windows mobile 5.0)
i am using c# (i am more experienced in vb6, but i need c# for the ipaq)

i just found out that the 3F character is sent when a parity error occurs
so maybe thats the problem ?

i made a lot of application which used the serial port (all with vb6 though, and 1 with c#) and i never got a parity error (maybe i was just lucky ;))

can anyone explain to me when a parity error might occur and what might cause it ?

any ideas are welcome as it will offer me something more to test and check and continue from

thanks in advance ;)
