How do I check to see that modem properties are set to the correct values (Windows 95/98/Me/NT)?

The steps to verify your modem properties are the same for Windows 95, Windows 98, Windows Me and Windows NT.

1. Choose Start > Settings > Control Panel to open the Control Panel window.
2. Double click on Modems to open the Modems Properties window, and you will see all the modems available on your computer. Select the Motorola Satellite Series Data Modem to highlight it and click Properties.
3. Select the General tab and verify the settings with the below figure. The Port (COM1 in this case) should identify the port to which you are connecting your Iridium phone via the serial cable. The Maximum speed should be set to 19200.
   • Port: Communications Port (COM1)*
   • Maximum Speed: 19200
   • *In most cases COM1 will be used.
   *In most cases COM1 will be used.
4. Select the Connection tab and verify the settings below
   • Data bits: 8
   • Parity: None
   • Stop bits: 1
   • Cancel the call if not connected in: 60 secs
   • Disconnect a call if idle for more than: 15 mins
   Please note that the disconnect time of 15 minutes is just a suggestion, and that this will not affect connectivity or performance. This will disconnect your connection if there is no traffic and is useful if you forget that you are connected.
5. Select Port Settings and verify the settings with the below figure. Click OK.
   • Use FIFO buffers (requires 16550 compatible UART) should be checked
   • You may have to lower the Receive Buffer and Transmit Buffer settings if you experience problems communicating with your handset.
6. Select Advanced... and verify the settings with the figure below. Click OK and close all open windows.
   • Extra settings: should be blank
   • Append to log: should be unchecked
