It really depends on the LCD device you have (above all on its controller, if it have any).Many LCDs use the HD44780 (or equivalent) controller, if this is also your case then Google may really help you: interfacing a PIC microcontroller with a HD44780[^].

how to send "1" to a serial port and then receive the values the pic will be sending me after it received "1"

2 May 2014 by OriginalGriff

Firstly, stop opening and closing the port: it won't help and it may cause data to be lost. While the port is closed, anything received by the physical port will be thrown away...and it allows other applications to "grab" the port as well. And you don't need an event handler to pass the data...

Stay away from timers because they are "high level abstractions" of hardware. They are very incorrect and even more in comparisions. The error rate is to great to accept. Any looping is bad.Use some hardware high resolution API like Tick count of the processor. Maybe here is some useful example.
