I wanted to make 2 software uarts and ran into a strange situation. If I open a port and then close it in one sub routine, open a second port and close it in another subroutine, the program does not work. If I open both ports in the same subroutine, use them and then close both ports the program works. I can program around this. I just thought it was strange.
