Hello all,
I have an application that uses several different baud rates to communicate to different devices. I have an interrupt routine that reads in GPS messages once per second. Since the GPS operates at a different baud rate than other devices, I have to switch the baud rate in the interrupt (change TH1), and then switch back.

Periodically, I completely lose the ability to transmit serial messages (my code is still running, however.)

Are there any issues where changing the baud rate in an interrupt can cause this problem?
