Are you sure that the TS-7800 does this? I have not seen this when I have used
RS-485 on the TS-7800. Furthermore, I just now tried writing to a TS-7800
RS-485 port, using picocom, and I did not get anything echoed back. This sounds
like something in your wiring is reflecting the transmitted data back to the
TS-7800, and by the time it gets back, the transmitter has been turned off and
the receiver turned back on.
