USB-FTDI[UM232R] with PIC16f877a
Dear all,
I am new to the PIC uC and have just written a code for the USART function. I am using UM232r [USB module] to communicate with PC.
{ USB module:http://www.ftdichip.com/Documents/Da.../DS_UM232R.pdf
I am using page-14 settings of the USB}
Using serial cable connection, the same code works absolutely fine. As soon as I am using the USB module, it doesn't seem to work at all. That means my code is alright and there might be some error in the USB settings. :(
The TX section of the code [when using without the RX part] is working fine with the USB though but it's not working for the RX section. In my UM232R USB circuit, I have connected the handshaking pins [RTS# and CTS#] to each other and not to the PIC. It works for the TX part. I am not sure whether this is causing the problem when I am receiving the data.
I will be really grateful if you could have a look it.
Many many thanks.

Ps: I am using TERMINAL on PC for this task.
