I've started using button tags in htlm and having onclick post a string to the pic. I pass the string into the same command interpreter I use for everything else. Everything else includes tcp connections, usb, rs232, and system configuration. System configuration is just a bunch of lines of text saved to external flash. On power up, it's passed to the command interpreter. Harold --=20 FCC Rules Updated Daily at http://www.hallikainen.com - Advertising opportunities available!
