PPP with Modems

The PPP interface provides a connection using modems over a telephone line. Connect modems to the APs with null-modem (straight-through) serial cables. Designate one AP as the Originating AP and the other AP as the Answering AP.

Configure the Originating AP with dial-out information to the answering AP. The answering AP waits for the originating AP to dial in to it.

The AP supports modems that use the generic Hayes Smartmodem command set. The AP uses Hayes commands and is capable of working with various modems of 19200 baud or faster. 3Com does not support modems the company has not qualified.
