To simplify debugging, I'm contemplating connecting two serial devices (gps - MT3339 and sat-comm - Iridium 9602 ) to the same RX/TX pins on the msp430f5529lp (port pins P3.3 and P3.4). They are never powered at the same time. This uses Serail1 for GPS fixes and Sat-Comm messages, and leaves Serial free for debug. Are there problems with doing this?
