I have a TI Microreader here, but have used in only to communicate with a PC. I think in your case the 2 most important issues are the voltage level (microreader is at RS232, PIC at TTL) and the signal polarity (PIC UARTs use inverted voltage polarity on the Tx and Rx pins compared to RS232). > I also tried to just blink an LED, or set a port pin to a value based > on the value of RCIF, but nothing happened.

I'm not familiar with the compiler you use, I have only used the CC8E compiler. So I cannot help you with this..
