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.
Sorry I didn't get back. Thank you, that was where I missed it.

Bit of a lull as I wait for a new meLabs serial programmer. For some reason the 18F2550 decided to become a heating element instead of a processor. Alas, it lived a good life.... Couldn't be EOC, could it? (Excessive Operator Carelessness). Had to dig out an old laptop that still had a parallel port to run the EPIC programmer.
