Parsing strings received serially.

Hi guys,

I Havent used PBP for quite a while, and I'm afraid my memory is getting rusty.

I need some help with string parsing.

I get a stream of data over the serial port in the format !Vxx=yy$

Where, !V are common start bytes, xx is a 2 digit integer in decimal, followed by "=", and followed by another decimal yyy which could be either single digit, double digit OR 3 digit. And lastly, "$".

I'll need to fork off to different subd, depending on the value of xx.

What would be the best way to do this?

Thanks in advance, guys!
