That said...it's totally cool to hack your board If you want to open serial ports COM5-COM7 (on GoBus ports 1-3 respectively)
I was trying to open a GoBus COM port as you mentioned here. Is there some trick to using these COM ports on the GoBus? I saw that there is a TX pull-up pin coming from the micro for each of the COM ports on GoBus sockets on the Netduino 3 (pin 43 for COM7). Does that pin need to be configured as an output and set to true? If so, how do I get to that pin in code?
