Hi Tom,

you don't need to include "modedefs.bas"
(it does neither help nor hinder)

Mode 16468 ($4054) means 9600 8N1 driven inverted.

This mode is ok if you connect PORTC.6 of the PIC directly to the RX Pin (Pin 2) of the DB9 connector
(no RS232 driver)


I think the problem is caused by the LED you have connected to that Pin, the LED is drawing too much power from the PIC output.

The PC-COM-Port is expecting RS232 levels (+/- 10V)
most COM-Ports work with TTL-levels from a PIC when connected directly to the PIC.
