Hi,
I want script which executes on EVERY machine
and (re)starts io-net
AFAIK, enum-devices script always starts some device drivers
(such as io-audio,io-graphics etc) although its were loaded.
And i wrote the following script. This script allows does not load some
drivers again.
But, may be exist some another better solution?
#!/bin/sh
#set -x
This script should be used to load io-net.
It allows for io-net to load appropriate hardware drivers.
In general this script is used in debugging purposes when it is need
to unload/load io-net offen.

Dear All,
I need to restart io-net on a QNX 6.1 standard installation.
I thought the right place to do it was /etc/rc.d/rc.local with the
following
commands:
slay io-net
devp-pccard
io-net -dpci_nic -dpcmcia_nic -ptcpip
Unfortunately things do not work out because devp-pccard is not started
yet
when io-net is called.
The build files use the command waitfor /dev/pccard, but the command is
not
available for the shell
By digging in the help, I found the “waitfor” can be used in the
enumerator
files.
Is it wise to modify them ? Would you suggest an other approach ?
Thanks,
Andrea.
