Hi Bo,
At 4800 baud, each byte takes about 2.1 mS.
The USART has a 2.8 byte buffer, so at around 6 mS the USART buffer will overflow.
In the DlyTime2 section, it will loop 50 times with a 2mS delay without checking the USART.
By the time it's finished, the buffer is very likely to have overflowed.
I think if you do the same thing you did in DlyTime1, and check the RCIF bit inside the loop, it will have a better chance.
And as you work on the rest of the program, look for any of those Evil PAUSE statements.
Anything more than 4ms will have to be broken in smaller loops with RCIF checks in the middle.
Added:
Another method might be to use ON DEBUG, with only the Delay routines ENABLEd.
Then it would be able to check RCIF in-between each and every statement in the delay routine without actually having to write the checks into the routine.
hth,
