You'll have to look at the driver to find out precisely what your system really supports; if you have no sources and no tty(4) manual page, all you can do is scream at your supplier. A regular V7 tty(4) manual page will help, but is not necessarily definitive. Do not bother looking for the ioctls whose names start with "DIOC"; they are ioctls for Bell Labs's internal "Datakit" local network, and should never have been in the released V7 at all. The kernel doesn't implement them, by the way. The FIOC ioctls should be described in ioctl(2). The MX ioctls are for the mysterious multiplexer (adjective mine), which is beyond human understanding. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
