I'm not a very good C coder, but that's less important. I'm hoping, if a user space screen reader is implemented, that it can be extended; e.g. perl, python, etc. The problems with this seems to be: 1. How can a userspace program get extended key sequences such as caps lock+i? Under Linux, I don't think that an API exists for this. 2. What about console output? There is /dev/vcs[a]x, but polling that a few times a second would be inefficient if the system was under load. The rest is relatively easy - Linux already has serial port devices if needed, and also speech dispatcher communications. I see no reason why a smaller subset of speakup (just an API to get keyboard/console input/output) couldn't be included into the kernel - it probably wouldn't change much, compared to the user-space adapter that would be using that API. This is similar to what the Jupiter project is doing; although that's all in-kernel. any thoughts? - - Tyler -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQFGeOZxTsjaYASMWKQRAt/WAKCsG0jwPECPii4+yQX6i4gO02UdXQCgmmuY e5jsV1bQGCZd+8LLWjwTHTs= =xOzu -----END PGP SIGNATURE-----
