5To save the RF Conﬁguration information to all APs with the same WLAN Service area, select Save ALL APs [F2].

This option saves the conﬁguration changes for the current AP, and sends two WNMP messages to all other APs on the Known APs table to update their conﬁgurations and reset them after the conﬁguration has been modiﬁed. You can execute this option only among the same hardware platforms and same ﬁrmware versions.

6Select Cancel [ESC] to disregard any changes made to this window and return to the previous menu.

Conﬁguring PPP To use a Point-to-Point (PPP) connection, choose the appropriate hardware connection (direct or modem). Verify the enable status of the serial port) in the System Conﬁguration menu.

PPP Direct

PPP direct is a direct null-modem serial cable connection between an AP and computer. To conﬁgure PPP direct, follow the procedure, below.

1Select Set Serial Port Conﬁguration from the Main Menu. The Serial Port Conﬁguration window will be generated.

2Set the Port Use parameter to UI.

1Select Set System Conﬁguration from the Main Menu.

2Set the PPP Interface to OFF.

3Press the space bar or left/right arrows to change the value.

4Press Enter to conﬁrm the change.

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.

The following modems qualify to work with the AP:

■Practical Peripherals PM288MT II V.34

■Supra Fax Modem 288

■USRobotics Sportster Modem 28.8
