The test result of FTDI RS232 RTS & CTS are FAIL.
The reasons are as follows
1. As shown in Figure 1, FTDI RS232 RTS hi/lo setting, I can measure the signal change at the measurement point of side A (IMX8).
But the signal change can not be measured on the test connector (B side).
2. RTS is the output signal on side A (IMX8)
Compare the circuit diagram with the TRS3232E datasheet, as shown in Figure 2.
Shows that A side (IMX8) RTS is currently connected to the output terminal of TRS3232E.
At present, the RTS signal cannot be measured on the B side, please help to clarify, thank you
