Chip 24FJ128GA306 has Hardware RTS/CTS flow control lines.
I can't see anything in the CCS #use RS232( ) that even mentions hardware flow control.
On earlier projects (PIC18) I implemented RTS/CTS in my code.
Does CCS have any functions to enable/use the built in Hardware RTS/CTS.
I some how don't think the hardware can do that automatically. I guess I'm being a little lazy and could study the data sheet some more. !
My question is:
Must I handle the UARTs built in Flow control ?
Thanks

It is in #use RS232. However _only__ if you enable buffering. Look again. It is a huge section entitled 'Flow Control Options', after the section 'Serial Buffer Options'. You can specify the pins for RTS/CTS, what level to use, and control the actual timing involved (there is a misprint in the manual here, with the FLOW_CONTROL_MODE option referring to RTS, when it should refer to CTS). SIMPLEX_MODE controls RTS.
Are you sure you are using the current manual?.

Thanks You nailed it.
As the V5.048 IDE debugger really is not working (it is being fixed, I hope)
I moved down to the V4.124 IDE and of course the help file does not include "Flow Control Options" in the #use RS232
