4. Modify the startup script to automatically start the driver:
cp /home/username/bbelec/drivers/MIport/rc.bb17d15x /etc/rc.d
WARNING: Do not overwrite
/etc/rc.d/rc.serial
if it already exists!
Note: These scripts will create the device nodes /dev/tty/M0/ and/dev/cum0
for each port, where the 0 is the number of the port.
If
/etc/rc.d/rc.serial
already exists append the commands from:
/home/username/bbelec/drivers/MIport/rc.serial
to
/etc/rc.d/rc.serial
The commands in
/home/username/bbelec/drivers/MIport/rc.serial
are:
#!/bin/sh
if [ -f /etc/rc.d/rc.bb17d15x ]; then
sh /etc/rc.d/rc.bb17d15x
fi

/sbin/shutdown –r now
Note: Only the root user and members of the “uucp” group will have
access to the driver. Add users to the “uucp” group as needed.
