Hi all

Im having a problem doing serout @ 9600 with 20mhz osc on 18f4550 (sending garbage chars)

I have the 18f4550 set up for usb operation pll*5 (20mhz osc in) and also want to use a pin for serout.

but even if i put DEFINE OSC 20 top of listing it sends garbage out the serout pin, BUT, if i change the DEFINE to "DEFINE OSC 12" it sends the correct chars out the pin EVEN though it has a 20mhz xtal attached ???, and of course the usb wont work with this define.

Any idea whats going on ?

Thx
