Choosing/Editing a Modem File
To configure a modem, we'll use the ADR Modem Configurer utility, as installed in the previous section. Many types of
modems are already provided with a modem configuration file. However, if the modem to be configured is not one of
the supported modems, a new modem configuration file will have to be created by editing one of the existing files.
To select a modem configuration file:
1. Look at the list of modem configuration files that are installed with the utility, as listed on page 9 of this Tech Note.
If you are installing one of those modems, you can simply choose that file in the ADR Modem Configurer Program
and skip the rest of these steps.
2. If none of the preconfigured files are appropriate for your modem, you'll need to create your own file. First, make a
copy of an existing modem file (e.g. genfld.mdm) and rename it.
Note If a DOS-style filename is used (i.e. it uses the 8.3 name format,) the same
modem file can also be used to configure the modem for use with Peek’s old
TDP software package. TOPS can handle full length filenames, as long as they
end with .mdm.
3. The modem file is an ASCII text file and can be edited in any ASCII text editor. In Windows Explorer, right-click
on the file and choose Open With...

4. From the list of applications, scroll down and choose Notepad. Unless you have another application on your
computer that also uses the .mdm file extension, you probably should go ahead and select the Always use this
program to open these files checkbox. (That way, the next time you double-click on any .mdm file, it will
automatically open in Notepad.)
