XThis is siomon, a serial I/O monitor for XENIX V. I know it works
Xon the 386 with 2.3.2, but it should work with any system that
X1. has select(S) [NOTE: 2.3.1 has a broken but fixable select].
X2. defines the serial I/O structures in the kernel with the public
X label '_sio_tty' (the console I/O label is '_cn_tty', BTW).
X
XSince XENIX curses.h and sys/tty.h both include termio.h (and the
X$#@*/! termio.h fil;es doesn't handle multiple inclusions),
Xyou need to patch your sys/termio.h file by:
X su root
X patch /usr/sys/include/termio.h < termio.h.diff
XThis enables termio.h to be included multiple times without error
Xif and only if #define TERMIO_HACK is turned on. The header
Xfile will behave exactly the same as it always did if
Xthis define is excluded, so you won't get lulled into thinking this
Xdesirable behavior is the same in all the termio.h's in the world
X(would that we could).
X
XTo make siomon after the patch has been done:
X1. cc -Ox -DM_TERMCAP siomon.c -s -o siomon -lcurses -ltermcap
X (you may have to omit -DM_TERMCAP if it is your default)
X2. chown root siomon -or- chgrp sysinfo siomon
X3. chmod 4111 siomon chgrp 2111 siomon
X
XYou may be able to hack it for other System V type systems by
X1. using nap() and rdchk() instead of select() (pre XENIX 2.3,
X no hope on vanilla System V)
X2. change xlist() against '_cn_tty' to ??list() against '_??'.
