Mike, every machine cycle T1 overflows and gives a "tick" to the UART. But Timer 1 is not generating any interrupt. Serial interrupt is another issue, well answered bellow.
Daniel



I thought the T1 counter incremented every machine cycle, until it overflows. And then the UART gets clocked.

Of course if you preload T1 with 255, it will overflow on the next machine cycle...


EDIT

I reviewed the OP and it states that T1 = 255....

So it does overflow ...
