RS485: testing loopback

I am using a rs232 to wire rs485 converter. I have shorted TX+ with RX
+ and TX- with RX- for 2-wire configuuration. A 120R termination
resistor is connected between TX+ and TX-.
I am using it in half-duplex configuration.
Is it possible to test loopback. Because in half-duplex either tx or
rx will be enabled.
I have not tried this. Just before trying want to check if this will
work.

No, it won't work in half duplex.
