Configuring RAS TCP/IP synchronization via serial port connection

This procedure involves actions both on Windows NT and on the Palm Computing device.

To configure Windows NT for RAS TCP/IP via serial port

1. From the Control Panel, open Modems. Make sure that a modem is defined for Dial-Up Networking Serial Cable between 2 PCs on the COM port to which the cradle is connected.

2. Set the speed for this modem to the baud rate you are using. The default is 19200.

3. Make sure TCP/IP protocol is installed. Select Start > Settings > Control Panel and double-click the Network icon. Click on the Protocols tab. If there is no TCP/IP entry, choose Add to install it.

4. Enable IP Forwarding (in the Routing tab of TCP/IP properties)

5. Under the Services tab, make sure that Remote Access Service is installed. If there is no entry for Remote Access Service, choose Add to install it.

   In Remote Access Service Properties, add Dial Up Network serial cable between 2 pc's for that COM port if the cradle's COM port is not in the list of ports.

6. Configure this entry to receive calls. In the RAS Network properties set encryption settings to Allow any authentication including clear text. In the RAS Network properties allow only TCP/IP client.

7. Configure TCP/IP. Allow clients to access the entire network. Assigning the TCP/IP addresses depends on your network. Contact your network administrator for details.

8. Add a user for dial-in access. Select Start > Programs > Administrative Tools > User Manager. Uncheck User Must Change Password at Next Logon. Choose the Dialin button, and grant dialin permission to user with No Call Back.

9. If the RAS COM port is the same one that HotSync Manager uses, shut down the HotSync Manager or any other applications that use the COM port.

10. Start the Remote Access Administrator. Select Start > Programs > Administrative Tools > Remote Access Admin.

11. Start the RAS service. Select Server > Start Remote Access Service. Choose to start the service on the local machine.

HotSync Manager or any other applications that use the serial port and the RAS service will not run at the same time. One must be shut down first for the other to run, as Windows NT prevents two different applications from accessing the same serial port. You have to stop the RAS service (Server > Stop Remote Access Service from the Remote Access Admin) before you can restart the HotSync Manager. Alternatively, you can use separate serial ports.

Once the RAS service is running, it is ready to receive connection requests via the serial port.

To configure a Palm device for RAS TCP/IP via serial port

1. Go to the Preferences (Prefs) panel and choose Network from the dropdown list at the top right of screen.

2. Choose the Windows RAS service.

3. Set the dial-in username and password.

4. Set the Palm to use the serial port.

   • For Palm OS 3.3 and above, select Direct serial.

   • For earlier versions of the Palm OS, set the phone number to 00 (zero zero). This is a special phone number that tells the Palm to use the serial port directly, instead of a modem.

5. Tap Details.

6. Set the connection type (usually PPP).

7. Set the DNS and IP addresses as recommended by your network administrator.

8. Tap Script and enter the following script:

   Send: CLIENT
   Send CR:
   Delay: 1
   Send: CLIENT
   END

   Tap OK until you are back to the Network Preferences

At this point, you are ready to test your TCP/IP connection.
