tcpdial command: Establish a manually initiated serial to IP
connection
tcpdial operates in an identical manner to tcpperm, except that establishment of the socket
connection is not automatic and must be initiated by the tcpdial command. The simplest method of
achieving this is to map a command using the Configuration > Network > Interfaces > Serial >
Command Mappings, such as, Command to Map ATDT0800456789 maps to tcpdial asy 1
217.36.133.29 -e0. Now, whenever the attached terminal device attempts to dial the number defined,
the router maps it to an IP socket connection. In this way, you can direct multiple dial commands to
the same or different IP hosts with other simple command mappings.
The tcpdial command is available only as an application command, and has no equivalent setting in
the web interface.
