If there are any issues or updates, post them and I will implement them, or just post new code. I just made this up based on my own routines from other uC's and stealing an idea from the MCC code (I liked the buffer count tracking variables), so this is not well tested code. You can change the buffer size in the header define. It uses a ring buffer to store the data received and the data to be transmitted. I included a main sample test to show how it works and the lib files eusart_lib.c and eusart_lib.h. So this is hardcoded 9600bps 8-N-1 sample. I'm sure there is sample initialize code out there that will generate the baud rate registers correctly. The baud rate registered are just set with a hard coded value. The Initialize is not a smart initialize. (I assume, haven't done a whole lot with PICs)
This code works with the "Enhanced Universal Synchronous Asynchronous Receiver Transmitter" (EUSART) module in the mid range 8 bits. gets also does not send the characters back, so if it's used for data entry, you will want to update it to transmit the characters back so the user can see what they are typing. You might want to edit it to ignore line feed characters. It looks like it is triggering on both the carriage return and line feed sent by my editor so I'm getting an extra blank line entered. v1.34 is the version of your compiler, it might be different if you are using a.

I have gets (get string) and puts (put string) functions implemented. From the PIC18F Peripheral Library Help Document found inside your compiler installation directory in. I re-generated the config bits, but that was it. Moved it over to a 16F1933 test board I have.
SERIAL LIBRARY FOR XC8 HOW TO
Something is odd with that and not sure how to get it working. Tried testing with my 12f1840 RGB boards, but I realize I am using the same pins for rx/tx as the debug pins.
