Tx(Pin 2) : Rx
Rx(Pin 1) : Tx
baudRate: 115200

I am trying to read registers using the following line,
uint8_t a = ZL.readHoldingRegisters(0x20AB, 2); Serial.println(a);

The instruction set of the motor driver is described below.

However, my RS485 instruction write function is working properly.

Can you please help here to solve the problem?

I have read other issues and specifically this: #127 but I couldn't understand.

Thank you in Advance.
