Status: Unverified
FACT(s) (Environment):
Windows 2000 Advanced Server
Progress 9.x
SYMPTOM(s):
Barcode scanner truncates duplicate characters.
Barcode scanner is used as input device.
Barcode scanner telnets to database server.
Connects character client to database through shared memory and launches application.
example:
Scanning a number sequence of 1223 is displayed as 123.
Duplicate values stop being displayed when database was moved from UNIX to Windows Server.
RO Systems TNVT telnet emulation software is the telnet application.
After telnet connection is established, barcode scanner launches telnet.cmd script.
Telnet.cmd script contains the following.
cmd /c c:\dlc\bin\_progres.exe -basekey INI -ininame
c:\wrkdir\progress.ini -p c:\wrkdir\login.p -pf c:\wrkdir\startup.pf
Runs the following procedure to duplicate issue.
DEFINE VARIABLE X AS CHARACTER FORMAT "X(40)" NO-UNDO.
UPDATE X.
pause 5 no-message.
output to c:\temp\output.txt.
put unformatted x.
QUIT.
no modifications have been made to the progress.ini file.
Redirecting scanner output to c:\temp\output.txt shows duplicate values.
Entering duplicate characters using the scanners keyboard interface works correctly.
Add
MULTITASKING-INTERVAL=3000
to progress.ini. Increase the buffer size values for data inputs.
Redirection out output to edlin, or edit Windows character application truncates characters also.
CHANGE:
Database server was moved from UNIX to Windows.
Progress upgraded from 8.X to 9.X
CAUSE:
Problem is not specific to Progress.
Since the problem can be reproduced using non progress character appilations.
FIX:
Contact Telnet software provider, and Barcode Scanner Manufactor for instances.
