Serial Port Drivers

[David B Stewart]

Does anyone have the source code for serial ports using the 
Signetics SCN 68681 DUART, which they are willing to distribute?  
In particular, these are the ports on an Ironics IV3220 Single Board Computer.

We currently have very primitive drivers for the ports, and unless I
some volunteers some source code, I will be embarking on improving these
drivers.  

The drivers that we need are UNIX like (eg open-close-read-write-ioctl), 
but for our own custom operating system.  As long as they are written in C, 
they can be useful at least as guidelines.

Thanks for the help,
