Using DialOut/EZ
  • The host application is reconfigured to use Windows modem devices installed on the virtual COM ports provided by the DialOut/EZ Redirector.
  • Alternatively, the host program may use the virtual COM ports directly.
  • When the application makes a modem call, DialOut/EZ obtains an available modem on a modem server located on the local network.
Key Results
  • The modem connection can be used for interactive access, firmware updates, diagnostics — all without depending on a functioning network at the remote location.
  • Security concerns related to the remote network are avoided, because that network is not used.
  • Multiple users of the host application can each initiate multiple sessions and share the total capacity of the modem server.
  • Multiple modem servers can be configured for failover to increase reliability of modem resources.
