Convert serial datasheet commands to a test driver

[m4hill]

Hi, i have a BV4108 serial backpack bought from http://www.byvac.com

I have the data sheet supplied here http://www.asi.byvac.com/downloads/BV41 ... aSheet.pdf

I have been trying to write a test driver for this backpack, with no luck so far. It communicates with terminal software just fine so i know my wiring is correct.

I know the 1st thing the display needs is a carriage return command to establish baud rate "13"
to send text to the display the command is "ad" then the text.

So i'm guessing the Init line should read something like this

Init=13,65,68 ?

to goto next line is acc0
so Gotoline1=65,68
GotoLine2=65,67,67,65,68
etc

Am i on the right lines here, as what i've experimented with so far doesn't seem to do anything!
Also, am i sending the byte string, hex or ascii values here as a could either be 65 or 96
Cheers
Martin
