Your quite correct Steve, it was your code which i found at http://www.picbasic.co.uk/forum/show...6F877+%4020MHZ

I didn't remove any of your signatures from the top header as they weren't on the code i found as above. All credits recognised though ;-).

Would you be kind enough to give an example of what you mean using the HSERIN command.

As in the interrupt code you are disabling the serial port first. Are you saying remove these lines, and then treat it with just the HSERIN command.

I am new to serial comms and often learn better from a quick example (if you could oblidge).

Many thanks,

Steve
