Hi Mike,
The software I am using in Linux (cajun - cajun.sourceforge.net)
requires
a serial display to work. What the linux driver does is emulate the
serial
display, and provides a /dev/lcd.
As I am not a perl coder, I cannot modify Cajun to use the app you
wrote,
And as I am not a C coder, I cannot modify what you wrote to behave like
the linux driver.
Unless there is something already around that can take input in the way
/dev/cuaaX
does, and then pump the data into what you wrote, I think that the
easiest way
to do this is to make a driver for FreeBSD that behaves exactly the way
that the Linux driver does.
