usart.bas Question about two lines of code

These two lines are in usart.bas, and used when there is a second EUSART, like in the 18F46K22.

RCInput As TRISC.Booleans(7), // As TRISG (2)
TXInput As TRISC.Booleans(6) // As TRISG (1)

These instructions would report the condition of the RX/TX pins. But it seems, not correctly, at least for the 46K22 as its RX2/TX2 pins are on PORTD, not PORTC as in the instruction, or PORTG as in the comment.

Likewise in usart2.bas, PORTG is used, so I would think that either usart.bas module would not properly work with a 46K22?

What am I missing here?

Nothing. The library modules were written long before many of the current chips existed, and haven't been updated.

You'll likely find other incompatibilities as well, esp with the ADC.

You can make your own copy of modules and with a few #defines make it compatible with any PIC you're using.
