Null modem with full handshaking for STM32F3DISCOVERY

I would like to control the E3631A power supply by RS232.

I use the null modem without handshaking (RX, TX and GND).

I can set the power supply but when I use *IDN? or SYSTem:ERRor? command.

The power supply didn't respond and no the signal at TX pin of the power supply.

When I use the null modem with full handshaking. I can set and get massage from the power supply.

Could you suggest for me?


Thank you
