Hi Melanie,

Thanks for the reply.

I thought that the SERIN and SEROUT were OK, but wanted to check.

Off topic, I'm really looking for a started guide to the use of PBC. The manual with it gives the syntax of the language tokens etc, but is not clear on use of directives etc and how to change the type of PIUC.

I thought that I should have simply been able to run your demo throug the compiler and get a HEX file at the end, but it barfs at the first @ directive!

I'll have a look through the forum again and post a note if I dont find anything.

Regards

Paulb
