This is (one of the) reasons I chose to use BRGH=3D1 and BRG16=3D1. I've not found any other evidence of problems with the EUSART on this group of devices. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
