FS-8704-11 Telnet Driver Manual 1. Page 1 of 6 Introduction The Telnet driver allows a user to connect to the FieldServer using a standard Telnet client (such as the Windows Telnet client).

To connect the Telnet driver to a serial driver, use virtual comports. Virtual comports are software emulations of real comports, and are connected in pairs. These connected pairs are ports VC1 and VS1, VC2 and VS2, VC3 and VS3, VC4 and VS4, and VC5 and VS5.
