It requires the following entry in the config file:

%%%
%%% {unix,[{telnet,HostNameOrIpAddress},
%%%        {port,PortNum},                 % optional
%%%        {username,UserName},
%%%        {password,Password},
%%%        {keep_alive,Bool}]}.            % optional
%%% %%%

To talk telnet to the host specified by %%% HostNameOrIpAddress, use the interface functions in %%% ct, e.g. open(Name), cmd(Name,Cmd), ....

%%% %%%

Name is the name you allocated to the unix host in %%% your require statement. E.g.

%%%
   suite() -> [{require,Name,{unix,[telnet,username,password]}}].
%%%

or

%%%
   ct:require(Name,{unix,[telnet,username,password]}).
%%% %%%

The "keep alive" activity (i.e. that Common Test sends NOP to the server %%% every 10 seconds if the connection is idle) may be enabled or disabled for one %%% particular connection as described here. It may be disabled for all connections %%% using telnet_settings (see ct_telnet).

%%% %%%

Note that the {port,PortNum} tuple is optional and if %%% omitted, default telnet port 23 will be used. Also the keep_alive tuple %%% is optional, and the value defauls to true (enabled).
