Chapter 7: Installing Virtual COM Ports

Figure 7-3. The COMInst window.

Step 4: In the Map To: field, select the number of the virtual COM port to be assigned. The default Flow Control setting is None. RTS/CTS can be selected if used by the application program and serial hardware. The Serial Server must be set to match. The protocol TCP/UDP, IP address, and port number will mirror the settings of the selected serial server. Click “OK.”

NOTE: PCs may have hardware COM ports and devices such as modems, IR ports, or USB-based COM ports that are not currently connected. Try selecting a COM number above COM s4 if problems occur.

Windows XP provides a notice concerning Windows Logo testing for XP.

Figure 7-4. The Windows Logo Testing window.

This XP feature simply indicates that these drivers have not yet undergone the Microsoft® testing procedures required to use the Windows XP Logo on the packaging. Driver compatibility is not affected.

Step 5: Click “Continue Anyway” to proceed with the installation.

Step 6: After setting all Serial Server serial ports as virtual COM ports, click “Cancel” on the Found Server form.
