RE: [misterhouse-users] Mr House and IR Commander (UX17A) support...

Thanks for letting me test my deductive skills Bruce. :-)

Are you saying you could mod that source code you produced to record those 
other signals (DTR/RTS)?  Does the cm17a communicate in ASCII over those 
lines?  Basically how does it work?
