Using the DialOut/EZ Redirector on a Multi-User Operating System

This Technical Note applies exclusively to the Site Edition of the DialOut/EZ Redirector running under Microsoft Windows Terminal Services or the Citrix MetaFrame Access Suite.

Note: On a multi-user computer you can install only the Site Edition or TacServe Edition of the DialOut/EZ Redirector.

When installing the DialOut/EZ software on a multi-user operating system, the configuration of the client software and your modem server will be slightly different than for single-user operating systems.

Bear in mind that any DialOut/EZ COM port, like a COM port that interface to local hardware, can be used by only one PC application at a time.  Managing the use of DialOut/EZ COM ports by multiple users is a key issue.

In the instructions below, each user gets separate DialOut/EZ COM Ports and modem devices.

  1. Run the DialOut/EZ setup program.
  2. When the Select Ports Window appears, set up the maximum number of DialOut/EZ COM ports that you think your users will need. This could be one per user or more than one per user. Note: Keep in mind that some users may want to have more than one dial-out session active at one time and will need more than one DialOut/EZ COM port.
  3. The Windows modem installation wizard should now launch. This wizard allows you to assign a modem driver to each new COM port used. When you are instructed to assign a modem driver to the ports, select all DialOut/EZ COM ports.  This insures that all ports will be assigned to the same modem driver at one time. 
  4. Open the DialOut/EZ Control Panel.  You should now see all of the DialOut/EZ COM ports that were created previously. Assign to each port the IP Address and Port Number of the hunt group on the modem server. 
  5. Each user will now only use the DialOut/EZ COM ports assigned to them and the modem server will automatically give them the next available modem.  If no modem is available, the user will see an error message from the PC application using the COM port.
