Please give me some example for RS485 with automatic hardware flow control when interfacing with Energymeter...Tried a lot but not able to receive anything from energymeter.

I have connected my RS485 automatic hardware flow control with energymeter and with the help of that, tried to transmit the query 01 04 00 21 00 02 (forf voltage) along with CRC check ....uint16_t ModRtu_CRC(uint8_t buf[8], int len){ uint16_t crc = 0...
