To get a PDA to interface to RCX is easy, i am right in thinking that TV
remote is the same freqency etc as RCX? If so go to pdawin.com and get
TVRemote http://www.pdawin.com/tvremote.html i use version 3.1 which can
learn commands, and we can display this on the PC and control from PC.
Simple! ;)
Also you could add a wifi card and PC Card expansion jacket and do control
wirelessly not via USB. Please also not control here could be direct
control, or your programme clicking screen like a macro.
