Here is what I haven't learned yet... I would like to recieve a few characters from the serial port and send a bunch back. I'm not sure how to work with this in the memory. If I want to recieve 3 characters first, I can store the first byte to some memory location, then I increment the address. I'm just not sure how to refer to an address rather than a number or literal. For this particular string I could refer to it in its exact location in the general registers.
Are there any routines for storing strings and sending them serially??
I would really like to move over to the PIC18 to get away from this paged memory but the web lacks many examples. At least its not too different.
