Start bit

[Tekky]

Many thanks for the info. Since posting I have looked at several serial comms
sites and seen that the start bit is necessary for synchronisation. I have been confused
by the PIC Basic literature not stipulating the fact the start bit must be present in the routine. Again many thanks.

The start bit is already there. You don't need to ad it. Standard serial comms = 1 start bit
followed by 8 data bits, followed by the stop bit, which is just an idle period where the TX
pin is held at idle logic for one bit period before the next byte can be sent.
