    Serial Rx Only

    Wondering if it's possible to use only the Rx or Tx pin of the Serial port ( specifically on pin 8, Serial3, of Teensy 3.1/3.2 ). I'm using the Audio adapter board which remaps the SPI mosi pin to pin 7, which is the Rx pin of Serial3. I would like to be able to still use the hardware Serial3 port though at the same time, with pin 8 as Serial3 Tx pin, and pin 7 as SPI Mosi pin. Anyone ever try this? I know it would be a low level io pin remapping, but just wondering if the hardware is capable of doing this at all. Thanks in advance!
