Debugging an Application Program

Setting Up the Terminal for a Debugging Session

Initiating a Debugging Session From the Terminal

Debugging an Application Program
In Direct Diagnostic Mode, a program developer can use debugging
software running on a diagnostic computer to monitor an application
program running on the Omni 3200 terminal, as well as test and
validate the program code. Debugging via modem is not supported.
The AX.exe debugger software, which is included in the TXO
Workbench, Version 4.1, includes a set of debugging commands that
provides extensive remote control of the terminal. The debugger
software links the program command line running on the terminal to
source code stored on the diagnostic computer's disk drive.
Before using the Omni terminal's debugging support feature, your
system must meet the following requirements:
• An application must already have been downloaded to the
terminal.
• The debugging computer must be connected by a VeriFone serial
cable to the terminal's 'RS232' port.
• The host computer must run debugging software (such as
AX.exe) that is compatible with the Omni 3200 terminal.
• The terminal's CONFIG.SYS file must contain a variable stored
under the *D record key, as described above in the section on
remote diagnostics.
The procedure for initiating a remote debugging session from an
Omni 3200 terminal is identical to the procedure for initiating a
remote diagnostics session, as described in Table 27 above.
When the *D environment variable has been stored on the terminal,
you can select the Debug menu item you want to execute from the
AX.exe Project submenu.
