Hi All,
Background.... We have found an unusual niche for lynx:- our warehouse management system employs "RF-guns" (small screen WiFi units with barcode scanners, see Intermec CK70 etc ) There are hundreds of units on the market, and to be able to use them all, we run the RF-gun's telnet equivalent program and then run lynx inside that. The various screens needed by our application are HTML pages (almost exclusively "forms") that are generated by a cluster of cgi-bins usually accessed via 'lynxcgi:' These RF-guns cause their laser-scanners to act like key-strokes. So when the user scans a barcode, the data is pumped into the current field on a form, and the cgi-bin eventually sees this as a classic "QUERY_STRING=" environment variable. My problem.... Most barcodes are a single field.... supermarket-product-code etc. no issue. one-scan-to-one-form-field... easy! Even QR scans. However there is a class of barcodes that contain sub-fields, and some of those sub-fields are allowed to be of variable length. The embedded sub-field-terminator is always rendered by the RF-gun as ASCII-GS (Group Separator, 0x1d, 035) (see GS1 specification and CODE-128 symbology... nicest web-site is www.adams1.com, if you have a spare few days!!) That ASCII control character is being silently suppressed from the input, and I need a way to allow it to come through to the QUERY_STRING. Actual display of the code-point is (from my point of view) optional! help! Cheers Mark ;-) PS.. our current version is 2-8-7 across many platforms, but 85% are now Linux (RedHat)... Happy to update, especially if the character gymnastics are changed. tools> tools> r file *lynx* isislynx.hp.hpux: PA-RISC1.1 shared executable dynamically linked - not stripped isislynx.intel.linux: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.2.5, not stripped isislynx.intel.linux64: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, not stripped isislynx.intel.solaris: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), not stripped isislynx.risc.aix: executable (RISC System/6000 V3.1) or obj module not stripped isislynx.sparc.solaris: ELF 32-bit MSB executable, SPARC, version 1 (SYSV), dynamically linked (uses shared libs), not stripped tools> tools> Mark Dewhirst | Development Manager | Microlistics Email: <mailto:[email protected]> [email protected] Mobile: +61 419 306 940 Phone: +61 3 9326 7422 Website: <http://www.microlistics.com.au/> www.microlistics.com.au microlistics_2013
