using microstudio for boot loader but have tried no loader with the same results using a serial lcd from redbinary lcd is 2 * 16 it does display its strartup message so assume electrical is ok they onmly deal with c programing not much i know about that (nothing)

Here's your code with a couple of tweaks, have not tested it though:

thanks for the reply will try this have moved display over to a 628a and get
fairly good some garbage dont know what that is

also trying to send a escape sequence to set up the serial chip

but that does not work any ideas on this tried
dec 27 or hex 27 or "<esc>" not working
interesting will not display esc here with the <>

also why the garbarge do want to move this back to 677a so will be trying your setting
again thanks for the feedback

Did you put a max232 or similar device between your LCD and PIC?

Ioannis

[jcleaver]

tried it with and without max works better without

does not seem to mater still get garbarge (some) also displays corectly

and unable to fiqure how to setup chip escape sequence

[Ioannis]

It can't work with both cases (with and without max232) using HSER commands! Are you sure of what you are doing????

I never used any Serial LCD's so I don't know of the ESC sequences. But with Serout commands you can drive a PC without MAX232. I am not sure if you can drive a slave device too... I'd use a MAX232 for sure.

If this: http://www.redbinary.com/sld01a.php is the LCD driver you're using, then it looks like you'll want to use 9600 non-inverted. It should also work directly connected to your PIC hardware USART pin.
