COM/IP Product Tour

   

Back to the COM/IP Product Page

 

The COM/IP Control Panel

  
  • COM/IP virtual COM ports appear in the list.  Selecting each port shows the current Init String setting for that port.
  • The Select Ports button lets you add or remove virtual COM ports.

 

Selecting Virtual COM Ports

   
  • The Select Ports window shows a list of COM ports (in the range of COM1 through COM4096). This list omits COM ports that are already used by other Windows device drivers.
  • COM/IP creates a virtual COM port for each of the COM ports that you select.
  • If you deselect COM ports, COM/IP removes the corresponding virtual COM ports.

COM/IP Virtual Modems

   
  • When you add a new virtual COM port, COM/IP initiates the Add Modem sequence that allows you to install Windows modem devices.
  • In the example below, a COM/IP virtual modem has been installed on each COM/IP virtual COM port.
  • Each COM/IP virtual COM port can be used directly or through the corresponding Windows modem device, depending on the needs of the application.

COM/IP Port Monitor Activity Display

   
  • Right-click the system tray icon and select Port Monitor to see a real-time display in the Activity tab.
  • This example shows a connection on COM7 as the result of issuing a modem dial command ATD world.std.com[23]

COM/IP Port Monitor Trace Display

   
  • The Trace tab in the Port Monitor shows all activity on virtual COM ports.
  • Trace Options allow you to select the COM ports to be traced and optionally copy trace data to the Windows debug channel.
  • Trace data can be saved to a file for later analysis.
  • This example shows the result of issuing ATD192074137005[23] to the COM/IP virtual modem. The endpoint is a UNIX system that issues a login prompt that times out after 60 seconds and then terminates the TCP/IP connection from COM/IP.
