Hi
I am assembling a small project from parts I have in my storage bin. This project is using an LCD display. I have difficulties displaying anything but the cursor and some "X's". I am using an NOS 14M chip along with a LCD117 driver chip, ordered long time ago from PH.Anderson (RIP) Here is my short test code for the display:
I am using pretty common 2 x 16 LCD display QC1602. Datasheet here: https://www.mpja.com/download/QC1602a.pdf
The LCD117 driver chip label says: LCD #117 9600 baud, my code is using 2400 baud. Is that the problem?

Code:
High 0 ' Be sure Tx Pin is idle for some time
Pause 5000 ' wait for PICAXE LCD to boot
SerOut 0, T2400, ("?G216") ' configure LCD as 2 X 16
main:
SerOut 0, T2400, ("?f") ' clear the LCD and home the cursor
Pause 100
SerOut 0, T2400, ("PICAXE LCD117") ' send text only, first line is automatic
SerOut 0, T2400, ("?i?iPicaxe&LCD?n")
Pause 2000 ' pause to admire
SerOut 0, T2400, ("?f")
SerOut 0, T2400, ("?0?1?2?3?4?5?6?7?n") ' display special characters
SerOut 0, T2400, ("That's It")
Pause 5000 ' pause to admire
Goto main
