[mythtv-users] extra digits

[Sreeram Kumar]

Thanks to all of you for the suggestions. I am using
#!/bin/sh
REMOTE_NAME=blaster
for digit in $(echo $1 | sed -e 's/./& /g'); do
irsend SEND_ONCE $REMOTE_NAME $digit
sleep 0.3 # note, you may have to tweak the interdigit
delay up a bit
done
irsend SEND_ONCE $REMOTE_NAME select

as the script. I changed the repeat count to 3. Still
I see the problem. What could be the issue? 

Also, I tried the script below but it drives the
dishbox with the first digit only whereas if I capture
the log I see all the three digits.

#!/usr/bin/perl

# make sure to set this string to
# the corresponding remote in /etc/lircd.conf
$remote_name = "blaster"; 

# Let's assume you don't need to press enter after you
punch in a
# channel number. Change this to 1 if your cable box
expects you press
# enter after each command
$needs_enter = 1;

# Change this to point to your rc executable
$rc_command = "/usr/local/bin/irsend";

# This subroutine actually sends the signal to the
cable box
sub change_SIGNAL {
    my($SIGNAL) = @_;
    system ("$rc_command --device=/dev/lircd1
SEND_ONCE $remote_name $SIGNAL select");
    sleep 0.4
}

$SIGNAL=$ARGV[0];
open F, ">> /var/log/channel.log";
print F "channel changing $SIGNAL\n";
close F;
print "channel changing $SIGNAL\n";

# Checks if $SIGNAL begins with a digit
# If it detects that the string is made up of digits,
then it puts
# spaces between the digits.  Ex. 1234 becomes 1 2 3 4
if ( $SIGNAL =~ /^\d+$/ )
{
    my $length = length($SIGNAL);
    my $counter = 0;
    my $temp;

    while( $counter < $length )
    {
        $temp .= substr($SIGNAL,$counter,1) ." ";
        $counter++;
    }

    change_SIGNAL($temp);
}
else
{
    # argument we passed was not made up of digits, so
it must be a
    # command that does something other than channel
changing on the
    # cable box
    change_SIGNAL($SIGNAL);
}

# Do we need to send enter
if ( $needs_enter )
{
    system ("$rc_command --device=/dev/lircd1
SEND_ONCE $remote_name select");
}

If this is happening with the serial IR receiver in
MythTV, you can 
verify this by using irw from the command line. In
this instance you 
need to check and adjust the repeat values in your
lircrc as Paul 
states. 

If this is happening with the serial IR transmitter
(which is 
controlling an external cable box via IR) you might
want to check/post 
your channel change script and check your freqid
values in the channel 
editor.
