You cannot use C native libraries with TINIOS.  You will have to use 
assembler as no C compiler we have found will work within the 
restrictions.  No direct usage, no indirect usage, no taking interrupts 
without calling system functions, restricted XSEG memory usage, etc.

I am not familiar with the Serial0IRqHandler function.  Is this a built 
in SDCC function label?

Your code looks fine.  If you are locating this code at 0x490000, you 
will have to put a vector at 0x0000XX to your timer3_isr() so that the 
interrupt will get to your code.
