① If there is no overflow, m bytes data must be transmitted within n seconds, then the transmitting time of M
bytes data:
If n >2T, then data will not overflow, USR-N540 can work normally. Just need keep n>T under baud rate 9600.
3.7.10. Synchronous baud rate (RFC2217)
For encryption during data transmission, devices change data bytes, baud rate, parity and so on. USR-N540
supports revise serial parameter accordingly.
