Pic16876A and USART not able to trasmit data

Hello guys. I am using this code (hitech c) for sending and receving data with virtual terminal (proteus). When I type "1" and "2" when
the terminal has a focus I can proprely turn on/off a led on a portB. But the command "b" doesn't return a the string HHHHH. THe baund
is the same 9600..What's wrong? Any help? Thanks

}
}

Your "putch" routine expects a byte, not a string (as "HHHHH").
putch('H'); // will work ...

After any interrupt occurs and its flag (like TMR0IF, RCIF, TXIF) is set then you have to clear it so that interrupt can happen again.

Hi. Thanks a lot for your relplies.
I had to change in H in h and I was able to send the char. The only one thing now is that if I use Virtual Terminal it works like a charm, while connecting
COMPIM to TX,RX with Tera Term VT I am not able to send/receive data. I have created a pair connection COM2 for Proteus and COM5 for Tera Term. RC6 is connected
to RXD and RC7 to TXD. The serial data match, 9600, 1 bit stop, no parity..seem ok. Noboday has experience with compim component?

Sorry. It works now. RXD -> RC7, TXD-> RC6.

Recently it has been answered about how to send/receive data between Proteus and PC VT softwares. Search for Proteus and COMPIM in edaboard. Someone used a virtual port mapper to send/receive data between Proteus UART and PC Hyperterminal.
