The tmcuart_send command increases cpu usage on the micro-controller. Should multiple tmcuart_send commands be issued at the same time to a single AVR micro-controller, it could increase the load to the point that it introduces a failure. It could also lead to tmcuart_send transmission errors, which would cause retransmission requests, which further increase the load. Track and share mutexes so that only one tmcuart_send command can be active on a single mcu at a time. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
