Erik Malund said:
get rid of the function calls in the ISR

Why are you fiddling with the ISR at all?!

The Keil INTSIO and INTSIO2 examples provide a ready-to-use implementation; you do not have to fiddle with anything - apart, possibly, from the buffer sizes.

Just take the INTSIO (or INTSIO2) code as-is, and concentrate on using getchar to get your characters, and putchar (or printf) to send them!
