Re: [Gumstix-users] problem with serial port

[surendranath g <sur...@ya...>]

Hi All,

I have a serial LCD with controls( Crystalfontz)
connected to gumstix. The display works but the
controls dont. I complied using gumstix g++ compiler.

http://www.crystalfontz.com/products/633/index.html

The same LCD works fine on redhat linux. Both display
as well as controls.

Any suggestions please? I am very close but I cannot
make it work.

thanks in advance
Surendra
