The modemcap edit Command

To add entries to the modemcap database, the administrator can use the modemcap edit
command followed by the database name: modemcap edit modem-profile-name. Configurations
provided with the router cannot be modified. Administrators should create a similar
user-created entry with their modifications.
To create a user-defined profile by using an existing profile as a template, use the modemcap
edit new-profile-name template existing-profile-name command with the template
being the key parameter. This will create a profile with the name new-profile-name and copy
all settings from the existing-profile-name.

NOTE:Use care when removing modemcap entries. The no modemcap edit modemprofile-
name command will delete the entire entry, not just a single line. To
delete only one line from the profile, use modemcap edit modem-profile-name
attribute.
It is generally recommended that administrators specify the type of modem that is connected
to the router. This reduces the probability of error and hastens the configuration process.
