Subject: [PATCH] fix(serial): Unblock if the queue is full
For some reason a portYIELD() is not enough to give the serial task the
option to run. I tried vTaskDelay() and that works. To not block more than
needed portYIELD() is still called when the queue is not full and only
call vTaskDelay() when it is full.
Closes #218
