TTY Port Manager directory
The "TTY" management interface directory allows you to control the state of the available TTY interfaces (TTY
ports). Moreover, it is possible to issue one "DTR drop" to the TTY interface that will clear the connection and re-
initialize the selected TTY interface.
Applications can use the context of this directory to retrieve the information about the last processed call
(detected protocol, bit rate, calling party number, ...) and use this information for example for call-back.
