18.16.1 Description
Establishes a transparent end to end communication with an already connected TCP or UDP socket via the
serial interface. The data can be sent to the socket and can be received via the serial interface: the HW flow
control usage is strongly recommended to avoid data loss.
The transparent TCP/UDP connection mode can be exited via the +++ sequence, entered after at least 2
s of suspension of transmission to the port. The socket will remain connected and communication can be
re-established any time.
commands allow the configuration of UDP and TCP
direct link triggers.
When using Direct Link with UDP sockets, if no network signal is available, outgoing UDP packet may be
lost.

The HW flow control is not supported.
