1. Introduction 

The Telnet driver allows a user to connect to the FieldServer using a standard Telnet client 
(such as the Windows Telnet client). A command prompt is provided which allows the user to 
request specific driver functions. Presently, the following functions are implemented: 
 

1.  help / ?: lists available commands and states their functions. 
2.  port: this allows the user to take over a serial port. 
3.  linefeed: this allows the user to control sending and receiving of line feeds in association 

with carriage returns. 

4.  echo: allows the user to determine whether characters typed into the Telnet terminal 

should be echoed by the FieldServer. 

5.  verbose: allows the user to determine the level of detail of diagnostic messages. 
6.  tab: allows the user to select substitution of received tab characters by space characters 

 
The driver will support up to 5 concurrent Telnet sessions but will not allow two sessions to 
control the same serial port.
