always coming in ErrorRecived Event and saying Frame Error ID 4,
so i checked this source at different com port and working nicely and i think this is Panda-s Bug
Is it FEZ Panda or FEZ Panda II?
What SDK are you using?
What do you have connected to the COM?
Its a Fez Panda,
SDK 4.1
i have connected GSM Modem but not worked, and than GPS antena but stil nothin,
i am sure that in Source is everything right
How about connecting the RX pin to the TX pin and seeing if you can get a loop back?
