Hello all, Has any one implemented a pty(4) (pseudo terminal) device driver for minix? How about modifying the tty driver to handle dumb IO cards like the AST 4-port board using a single interrupt? If either of the above modifications exist, especially for Minix 1.5 on a PC (either regular or 386 mode), where can I get them from? Thanks a bunch, -- Jonathan R.

It runs in user space, as an extra server process, to keep the kernel as small as possible. I am, however, still having some problems with flusing- I need a way to tell the CLOCK driver to send me a 'wakeup' msg every N millisec... :-( Comments, anyone? > How about modifying the tty driver to handle dumb IO cards like the > AST 4-port board using a single interrupt? I did that, and it works fine. However, if you do not install NS16550 UARTs on the board, MINIX has serious trouble with keeping up with the interrupts... :-) > If either of the above modifications exist, especially for Minix 1.5 on a > PC (either regular or 386 mode), where can I get them from? Send me email, and we'll take care of it. > Thanks a bunch, Green ones? :-) Fred van Kempen
