Dear E2E,
After RS232 transceiver, connect a long cable like 12M and then floating it. will it cause wrong detection issue?
Actually, it should connect to PC. When they disconnect it on PC side, but the cable still connect on system side and it looks like floating.
CPU is still doing the detection RS-232 port even the cable is disconnected on PC side so that CPU pending in this step.
Could you guide us the reason?
BR,
Jason
