Some user applications may require a file with the extension .CNF, to hold translation tables and other communications data. A .CNF file is in binary format and can only be edited using the CnfEdit
program. Several different options can be modified using CnfEdit
. Some are not used with current products, but are retained for compatibility with older gateway products.
- Take great care when changing .CNF values — do not change a value unless you are sure that the new value is valid.
- When you update a .CNF file, the changes do not take effect until the product using the file is restarted.
|To use CnfEdit
- From the Start menu, open a command prompt by clicking Run, then typing:
- Use the cd command to go to the directory containing the .CNF file to be edited.
- At the command prompt, type:
- Edit the .CNF file, then press Enter.
The File Selection screen is displayed.
- Type the name of the .CNF file you wish to edit, then press Enter.
The Configuration Categories menu is displayed. The column on the left provides a list of six categories. When you move the cursor over a category name, the column on the right provides a list of all the options in that category.
- Move the cursor over the category containing the options you wish to edit, then press Enter.
A new screen for editing the options in that category is displayed.
Categories and Options
||Option / Description
|IA Level Data Entry
||Airline code. The airline code will be set correctly when you receive the .CNF file. Do not change this code unless you are sure that the current code is not correct. If you do not have a working code, use
|Interchange address. Retained for compatibility with other gateway software. Do not set any values for this parameter.
|Host type. The host type will be set correctly when you receive the .CNF file. Do not change the host type.
|00||Any host type not listed here.|
|03||British Airways (BABS)|

||Retained for compatibility with other gateway software. Do not set any values for this parameter.
|Screen Translate Tables
||Because screen translation is a two-way process, two screen translate tables are supplied with the correct settings for your host. One is used to translate data going to the host; the other is used to translate data coming from the host. Do not change the setting unless you are certain that you are entering correct values.
Any value may be entered into the tables and very little validation is carried out, therefore, the user must ensure that the data input is correct.
||This screen displays all the items in the configuration file that are associated with communication between the gateway and the host. Care should be taken when changing these values as it is possible to select combinations of values that will prevent data transmission.
The HELP SCREEN at the bottom right of the screen will display further information about the item situated at the cursor, and also indicate the type of data expected as input.
||Because printer translation is a one-way process, from the host to the printer, only one table is required. Do not change the setting unless you are certain that you are entering correct values.
Most printer character translations will be the same as the display translation. However, some characters will be different. No more than 15 differences are allowed between the display and printer translation tables. If there are more than 15 differences, a warning message is displayed. At this point, it is possible to edit either table until only 15 differences between them are outstanding. The file cannot be saved if there are more than 15 differences.
||These options are not used.
