Question of using multiprogrammer board with RS232 board

[ke]

It is known the RC6 and RC7 should be set as transmit bit and receive bit respectively for doing hardware UART function, if I plug the RS232 board into PORTE of multiprogrammer, can I still generate the hardware UART by settting up the RE6 and RE7 instead. Thank you.

No - the pins for the hardware UART are fixed and must be RC6 and RC7 for the 16F87x family (other chips may use different pins).

If you wanted to use porte, you would need to create the UART functionality in software.
