when you inset a usb device your computer asks what it is. "imma usb to serial port device" it says "sorry, i got nothing here for you kthxbye". whereas the touchscreen says "imma 3m microtouch touchscreen" and the computer goes, "yeup i got your files right here you can speak to me"

a usb to serial doesn't just change from one pinout to another, it's a whole different protocol.

can you adapter a parallel to 25pserial to 9pserial to ps2 to usb? yes.



does it work? no.

Make a symbolic link from /dev/ttyUSB0 to /dev/ttyS0 and watch the magic happen. This works in Ion 2009.5+. Not sure if other kernels support.

Whatever the opposite of savvy is, that's me with Linux, heh, but just like I'm gonna find time to practice piano someday when I retire from the rat-race, likely when I'm in a convalescent home, I'll also be honing various coding skills, assuming the tree-bark cereal I eat for breakfast and avoidance of saturated fat lets me live long enough. ;)  But seriously..., thanks for the tip. Great to know it's do-able, and I might actually be able to figure that out if I could clear a few hours to fiddle with it and nag Linux pals only a tad bit.
