<div><p>Both external and internal modems can be used for PPP connections.</p>
<div class="section"><p>The command set used in a modem is normally described in the modem
documentation. The commands are used to reset and initialize the modem, and
to tell the modem to dial the telephone number of the remote system. Each
modem model has to be defined before it can be used with a PPP connection
profile because different modem models have different initialization command
strings. If it is an internal modem then the modem strings are already defined
for their use.</p>
</div>
<div class="section"><p>The iSeries™ server
has many modem models predefined, but new models can be defined through iSeries Navigator.
An existing definition can be used as a base for the new type to be defined.
If you are not sure what commands your modem is using, or if you do not have
access to the modem documentation, start with the Generic Hayes modem definition.
The predefined shipped definitions cannot be changed. However, additional
commands can be added to the existing initialization command or dial string.</p>
</div>
<div class="section"><p>You can use the electronic customer support (ECS) modem that is
shipped with the iSeries server
to establish PPP connections. On older systems, the ECS modem was an IBM<sup>®</sup> 7852-400 external
modem. On newer systems, the 2771, 2793, or any of the other supported Internal
modems may be used as the ECS modem.</p>
