It's a pattern that again appears shifted again regardless of 24byte-frame size, with the 7c in the end being a constant. Remember this for 2)... Unfortunately, the manual does not go into detail as to how the "no pulses mode" behaves. Out of a forum of OPENTX (t...
The pattern argument is a boolean set to true if this is a pattern match. function(nil, emsg) - An error or special character received; emsg can be one of: full - UART RX buffer full event; queue was reset (UART_BUFFER_FULL). overflow - UART FIFO overflow event; queue was reset ...

Read operations are part of SCI flags clear / data queue removal operation, only your code should read them, debugger should not touch them by any means. Shouldn't be a big problem for Tx function, perhaps it will function having SCI regs included in memory window, but really a pr...
