using a pic 18f4520 with getc()

May anyone advise me on why code on chip stops executing whenever it reaches a line with a getc() function. Do I need to include some libraries specifically for an 18F because with a 16F my code run smoothly on chip.

getc() waits for a character to be available, then it gets the character.
If you don't want to wait, then call kbhit(). It will check if a character
is available. If it is, then you can call getc(). If not, don't call it.
Read about these functions in the CCS manual:
http://www.ccsinfo.com/downloads/ccs_c_manual.pdf

The getc() function operates exactly the same way for 16F and 18F.
So does kbhit().
