thanx in advance
 
how much would you like to extend it? 1-2km? maybe 3?
you can simply use pair of 232/485 converters back to back...
 
So you can enable two PCs to cominicate whith each other whith those radio modules or whith IR like a TV remote.You can also use an laser insted of an LED to get a huge range.

i'd prefer rf , since it can be non-LOS. also writing an OS driver s/w , so that when these devices are plugged in..it behaves like say a communication channel/socket..etc..
