I have a PIC18F2450 installed in a PicKit 2 development board. The date sheet states:
"Enhanced Addressable USART: This serial
communication module is capable of standard
RS-232 operation"
Does this mean that I can connect the PIC directly to my Laptop serial serial port? If not, what additional hardware do I need? If so, what pins do I use? I plan on using the usart.pbp sample for testing.
Thanks,

The hardware serial will be on pins labeled TX an RX.
The hardware port sends and receives in TRUE mode. The PC uses INVERTED.
You will need something like a MAX232 chip to do the inversions.
You can use SERIN2/SEROUT2 with inverted mode and connect directly to the PC as shown in the PBP manual.
I have a PIC-P14 from Olminex that has a 9 pin port and Max232, will that work?
You can use the MAX232 from the board.
Might be fun getting the Pic18f2450 to plug into the socket :)
