yes

What is the make and model of the device you are trying to communicate with using Modbus?

[asadmehmood]

The issue has been resolved.
Changing the mode on both ends from ASCII to RTU solved the problem.

I swear I mentioned that...

Have you tried serial type RTU?

Anyway I'm no Modbus expert but to be honest I have never seen a Modbus device that used ASCII mode.

Yes, you mentioned it earlier, but the device manual explicitly states that "Modbus serial RTU and ASCII are supported." That's why I decided to try using ASCII. However, I still can't figure out why ASCII isn't working while RTU works perfectly fine.
