Well, it is possible... The keyword to google for is inputattach. A hint - it is a part of the linux-console package on sourceforge: http://linuxconsole.cvs.sourceforge.net/linuxconsole/ruby/utils/. You probably will have to write some glue driver. Or, probably, an easier option - write a user-space daemon that reads from /dev/ttyS0 and sends events to uinput. With this you don't need any kernel drivers - just a user-space daemon. HTH Guennadi --- Guennadi Liakhovetski
