I need to displey specific data on LCD 4x20 chr.
Data will be received via RS232 on PIC 16F877 on HSER on PIC MCU.
Did someone have best idea what to I send from PC to PIC?
Example from me:
If I send somethig like 1DOG that maybe I can decode in pic like print on LCD in first line DOG.
But what about if I want to specific also on wich position of disply I will display that word DOG ?
Do someone want help with some simple example PLEASE.

That problem is part of my idea to bulid some type of terminal with 4x4 matrix keyboard where I will send No of key waht was push ( I was test mister_e keyboard rutine and it work super).And also I need in same time to display return from PC on LCD 4x20 chr when specific key is push.

Any suggest is welcome please.
