Use
This is an internal call for use by the DualSerial? module and should not be used by user code. Instead of calling the HAL directly, user code should interact with the Serial* entries that DualSerial creates in DeviceFS.
Sends a byte. The routine is not expected to wait for FIFO space to become available; instead it should silently fail.
