There is a complete "COM/Serial port emulation" for those
devices. Both firmware (C code) and Windows code.
Your Windows application still opens and use a "COMx" port,
so either no change, or an easy development. I think that
there are links to the kit on the device specific web pages.

B.t.w, regarding "Exercise Bike Computer", I bought one of those
bikes some time ago. It came with an attached "computer" where you
get all sorts of data. Speed, distance, current road "profile" (up, down,
flat and so on). What I'd like to do was to build something that could
"soak" this information out from the device and transfer it to a PC.
There is no (documented) interface. The PCB has some
unconnected connectors, but I've not been able to find any
info on them, so far...

What I thought was to have a filmed sequence of some real
road, then code the up/down/flat parts, and have the PC to
dynamicaly change the brake on the bike. So you'd get the
impression of actualy riding on the real road. Well, maybe
not the project with the highest priority... :-)

Jan-Erik.
