Operating Systems HP-UX Configure X windows with both keyboard and USB barcode reader Post 303040900 by mnkaltenbach on Friday 8th of November 2019 12:34:02 PM
Configure X windows with both keyboard and USB barcode reader

Greetings.
Seeking guidance on adding a USB barcode reader (BCR) to an HP c3750 workstation with HP-UX 11.11 which is essentially configuring X windows to accept input from both a primary keyboard and a secondary keyboard that happens to be the BCR.

Historically, I have successfully added a BCR to an HP c3600 workstation with HP-UX 10.20 and a c3700 with HP-UX 11.11 by configuring X windows to accept input from both a primary keyboard and a secondary keyboard as stated above by adding the following lines to /etc/X11/X0devices :
Code:
Begin_Device_Description
Name    hp7lc2k.1               # USB Barcode reader driver name
Use     Other                   # This is an "Other" device
Path    /dev/hid/kbd_001        # Second keyboard device file
End_Device_Description

However, this does not work for the c3750. Adding the above lines to /etc/X11/X0devices does not appear to have any discernible effect on configuring X windows to accept input from two keyboards. A review of X windows generated logs shows no errors. X windows behaves as if no modifications where made to X0devices. The c3750 accepts input from either the primary keyboard or the BCR but not both.

NAME
GD::Barcode::ITF - Create ITF(Interleaved2of5) barcode image with GD SYNOPSIS
ex. CGI use GD::Barcode::ITF; binmode(STDOUT); print "Content-Type: image/png "; print GD::Barcode::ITF->new('1234567890')->plot->png; with Error Check my $oGdBar = GD::Barcode::ITF->new('A12345678'); die $GD::Barcode::ITF::errStr unless($oGdBar); #Invalid Characters $oGdBar->plot->png; DESCRIPTION
GD::Barcode::ITF is a subclass of GD::Barcode and allows you to create ITF barcode image with GD. new $oGdBar = GD::Barcode::ITF->new($sTxt); Constructor. Creates a GD::Barcode::ITF object for $sTxt. $sTxt has numeric characters([0-9]). plot() $oGd = $oGdBar->plot([Height => $iHeight, NoText => 0 | 1]); creates GD object with barcode image for the $sTxt specified at new method. $iHeight is height of the image. If NoText is 1, the image has no text image of $sTxt. ex. my $oGdB = GD::Barcode::ITF->new('12345678'); my $oGD = $oGdB->plot(NoText=>1, Height => 20); # $sGD is a GD image with Height=>20 pixels, with no text. barcode() $sPtn = $oGdBar->barcode(); returns a barcode pattern in string with '1' and '0'. '1' means black, '0' means white. ex. my $oGdB = GD::Barcode::ITF->new('12345678'); my $sPtn = $oGdB->barcode(); $errStr $GD::Barcode::ITF::errStr has error message. $text $oGdBar->{$text} has barcode text based on $sTxt specified in new method.
