In Topic: USB-Serial Module

That'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?

I have finally been able to post the results of a simple loopback test on the Netduino 3.


See the post here: http://forums.netdui...-loopback-test/


This test also has interesting findings for Netduino Plus 2.

As a follow-up, The loop-back test with flow control was successful using the Netduino Plus 2.  I was able to loop ~18K of data over the serial port and get back exactly what I sent repeatedly.


However, when I tried the same test on the Netduino 3 WiFi I only got back the first two chunks of data and it stops receiving data that is sent. 


I'll investigate further and post something in the Netduino 3 WiFi forum when I am able to.  At that point I will post a link in this discussion.

Hello Chris,


Thanks for the input.  I ran my test with flow control turned on and it worked perfectly. :)


I did not expect for flow control to be required because of the structure of the test: send some data and do not send more until you get back the data sent.


The issue that took me down the loopback test road was that I saw corruption of data when using an XBee on the SparkFun XBee shield.  I'm am excited to try that again now that I know I need to turn flow control on.


I appreciate the help!
