How can I configure my WorldPort 2400 to operate with the HP 95LX?

Open the modem case and change the internal switches. Set switch 3to ON.

Next, plug the modem into the AC adapter power supply. Connect the modem to HP 95LX using the serial cable, part number HP 82222A, and the serial cable modem adapter, part number HP 82224A.

Set the baud rate to 2400 on the HP 95LX. To do this press <COMM>, then press <MENU>. From the menu select settings config port baud 3 (for 2400 baud) quit quit. This will bring up the initial COMM screen. Enter AT&D0&W (the modem command) and press <ENTER>.

The modem should reply "OK" if it accepted the command. The WorldPort 2400 should be able to connect to the HP 95LX and operate with or without the AC adapter after this command is accepted. (This command tells the modem to ignore hardware handshaking. This command is written to the modem's internal memory. Until you change it again the modem should continue to ignore hardware handshaking.)
