I still get:
pppd: Couldn't determine if PPP is supported (no free ptys)
I tried creating a /dev/ptyp0 with major 2, minor 0 thinking it needed a pty to be available, but this did nothing. I did create the ircomm0 devices based on the ones on my RedHat box.
It should be noted that I didn't install from debian packages because I don't have a debian environment set up. What I did was extracted the files from the debian packages (using "ar x" and then "tar xzvf") and copied in the needed binaries and such. I guess it's possible I screwed something up. My next step is to try to do a chroot to a sane debian environment and try this process again.
But in the meantime if you can think of anything else I might have done wrong, I'm open to suggestions.
It's a Casio E-100 by the way. I am just trying that because it's the only IrDA device I own and I have nothing better to do with it.
