Please attach your project so that we can have a look into it.
Dear Embedd Holmes, Thanx for reply.
I have connected PC USB port to USB Connector (J10) onj board. And trying to do serial communication through this KitProg USB-UART port.
Plz find the attached project which works well. Program reply the same char for every received character.
However when I send stream of bytes through MODBUS testing software like Modscan32, ModbusTester, etc., these testing software gets hang. Same testing softwares work fine when connected on other COM port on PC.
One thing I observed recently is if I short P12_7 & P12_6(bypassing pSoc4) , same problem persist.
That means, there may be some pbm from PSoC 5LP Programmer & Debugger.

Dear Embedd Holmes,,
My guess was correct, problem is in PSoC 5LP circuit.
I took out Tx(P0_5) & Rx(P0_4) from pSoC4 CPU and connected externally to MAX232 IC and connected to Computer.
My program is now working as expected.
