Hello:

I am having trouble with a serial communication routine (which I didn't
write).
Specifically with the interrupt handling routine which is the following:

void interrupt com_int(void)
  /* Handle communications interrupts and put them in ccbuf */
  {
   disable();
   if ((inportb(portbase + IIR) & RX_MASK) == RX_ID)
   {
     ccbuf[endbuf++] = inportb(portbase + RXR);
     endbuf %= SBUFSIZ;
   }
   /* Signal end of hardware interrupt */
   outportb(ICR, EOI);
   enable();

  } /* com_int */

Which is previously declared in an include file as:
void  interrupt(*oldvects[2]) (...);

1. I do not recognize the declaration syntax [what does the (...) mean?
2. When trying to compile I get several errors, including:
       E2449 Size of 'interrupt' is unknown or zero
       E2141 Declaration syntax error at line 29 (the function itself)

I have seen that this is a rather common routine, anybody with 
experience in
serial cummunication? Any clue as how to get past the compile errors?

Thanks

Nathan
