Obtain a serial cable from your PDA manufacturer. Connect the serial PDA cable to the Globalstar data cable using a null modem (Radio Shack has a 9-pin null modem). Set the baud rate of the PalmPilot serial port to 38,400. Your Personal Digital Assistant (PDA) must be able to use PPP via an external modem connection. A data cable from your PDA’s manufacturer and a null modem and/or a gender changer may be required. Use DHCP for your IP address and also for the DNS servers. Both of these types of addresses will be automatically assigned to your Palm when you connect to the Globalstar network.
