Change file permissions to: chmod 755 /etc/uucp/fix-intel # 'Fix' an Intel 14.4ex modem. # This script writes a configuration suitable for operation with IRIX # into the non-volatile memory in the modem. # -i for inbound use only # -o for outbound use only # -io for both # -m model to specify the model number, as in "-m 14.4ex" # -v for verbose debugging # -c cmd to add the string of Hayes-like commands, "cmd", # to the end of string of initializations. # -s bps to specify the DTE speed, either "19200" or "38400" # This script must be run by "root". # When this script is run, it sends the responses of the modem to # standard out. It ends by telling the modem to display all # of its parameters. If you do not see the right results, # first check the cable to the modem. # This script uses 'ttyd*' device names, so that it is not stopped by a # need for DCD. Since there is often a getty(1M) running on # a 'ttyf*', and since you cannot simultaneously open 'ttyf' and # 'ttyd', it is necessary to stop the getty in /etc/inittab # before using this script. If a uugetty(1M) is running on the # port, it need not be turned off, because this script will # temporarily disable it. # Additional local commands should be added to this file in the following # line or provided with the -c option loc="" # Use a line in /etc/inittab like the following with an Intel 14.4EX #t5:23:respawn:/usr/lib/uucp/uugetty -Nt60 -iintelin,conn ttyf5 dx_19200 #port 5 USAGE="usage: `basename $0`: -i|-o|-io [-m model] [-v] [-c cmd] [-s 19200|38400] portno" if test $# -le 1 ; then echo "$USAGE" exit 1 fi while getopts "viom:c:s:" c; do case $c in i) in=1;; o) out=1;; v) if test ! -z "$verbose"; then set -v fi set -x verbose="-v" ;; m) model=`echo "$OPTARG" | tr '[a-z]' '[A-Z]'`;; c) loc="$loc $OPTARG";; s) speed="$OPTARG";; \?) echo "$USAGE"; exit 1;; esac done shift `expr $OPTIND - 1` if test $# != 1 ; then echo "$USAGE" exit 1 fi case $1 in [dmf]*) port=`expr $1 : '.\(.*\)'`;; *) port=$1;; esac dev=/dev/ttyd$port odevs="/dev/ttym$port /dev/ttyf$port" if test ! -c "$dev"; then echo "bad port number: $1" exit 1 fi if test ! -d /var/spool/locks -a -d /usr/spool/locks; then LOCKDIR=/usr/spool/locks else LOCKDIR=/var/spool/locks fi LOCKD=$LOCKDIR/LCK..ttyd$port LOCKM=$LOCKDIR/LCK..ttym$port LOCKF=$LOCKDIR/LCK..ttyf$port # uucp wants a 10 byte string LOCKSTR=`expr " $$" : '.*\(..........\)'` LOGFILE=/tmp/fix-modem$$ # use factory defaults, except or including: # L2=medium speaker volume # M4=speaker on during retraining # X4=extended result codes # &C1=DCD normal # &D3=reset on DTR false # &Y0=profile 0 # *F3=RTS/CTS flow control # *Q2=fall back and then disconnect on bad line, but this makes the # modem die # *Q1=retrain # S0=1 answer the phone on 1st ring, =0 do not answer the phone # S2=128 to disable +++ escape for "security", but this cannot be # saved in NVRAM. # S25=1 be sensitive to DTR case "${model:=14.4EX}" in 14.4EX) rstcmd='&F' varcmd='L2 M4 X4 &C1 &D3 &Y0 S2=128 S25=1' infocmd='&V' model="14.4EX" ;; *) echo "unknown model: $model"; exit 1;; esac case "${speed:=19200}" in 38400|19200) ;; *) echo "unknown speed: $speed"; exit 1;; esac # Set S0=1 to answer the phone for pure input. # Do not answer the phone (S0=0) for pure output. # Do not answer the phone by default (S0=0) for combined # input & output, because uugetty will answer it. if test "$out" = 1; then modecmd='S0=0' elif test "$in" = 1; then modecmd='S0=1' else echo "$USAGE" # complain if neither in nor out is set exit 1 fi if test ! -w /dev; then echo "This does not work very well except for the superuser." exit 1 fi # fight the UUCP daemons and others for the port /etc/renice -20 $$ > /dev/null echo echo " If this effort to program the Intel \"$model\"" connected to port $port echo " works, you should see a series AT commands and responses." echo " The response to each command should end with 'OK'." echo " The last command should be followed by a list of all of the settings." echo # lock the device by all of its names rm -f $LOCKD $LOCKM $LOCKF echo "$LOCKSTR" > $LOCKD; ln $LOCKD $LOCKM; ln $LOCKD $LOCKF # zap any gettys or other users pids=`/etc/fuser -q $dev $odevs 2>/dev/null` if test ! -z "$pids"; then echo " Stopping processes currently using port $port\n" if test ! -z "$verbose"; then ps -lfp $pids fi kill -1 $pids sleep 2 fi pids="$pids `/etc/fuser -qk $dev $odevs 2>/dev/null`" # re-lock in case the other guy removed our rude lock files rm -f $LOCKD $LOCKM $LOCKF echo "$LOCKSTR" > $LOCKD; ln $LOCKD $LOCKM; ln $LOCKD $LOCKF trap "rm -f $LOCKD $LOCKM $LOCKF $LOGFILE; /etc/fuser -qk $dev $odevs 2>/dev/null; exit 1" 0 1 2 15 # start listening to the modem, after waiting for previous users to # disappear and allow us to open the ttyd* device. # Also keep DTR low in the hope of resetting the modem. while test ! -z "$pids"; do pids=`/etc/fuser -qk $dev $odevs 2>/dev/null` sleep 2 done rm -f $LOGFILE tee $LOGFILE <$dev & stty $speed -echo -icrnl -ixon -ixoff -isig clocal < $dev # Reset things. echo "AT $rstcmd\r\c" > $dev; sleep 1 echo "AT Q0 $varcmd $modecmd $loc\r\c" > $dev; sleep 1 echo "AT &W\r\c" > $dev; sleep 1 echo "AT $infocmd\r\c" > $dev; sleep 1 #prevent message about the death of the listener exec >/dev/null 2>&1
