AT+I Command Set (Continued)
Command
Action
STCP:<host>,
<port>,[<lport>]
Socket TCP – Open and connect to a TCP Socket. If the modem is not online, it will
automatically connect. The responding system is assumed to be a server listening on the
specified socket. Responds with the handle to the socket.
SUDP:<host>,
<rport>,[<lport>]
Socket UDP – Open, connect and optionally bind a UDP Socket. If the modem is not online,
it will automatically connect. Responds with the handle to the socket.
LTCP:<port>,<backlog>
Listen Socket – Open a TCP listen Socket on <port>. Allow a maximum of <backlog>
concurrent connections. Responds with a handle to the socket. A maximum of two listen
sockets are supported.
LSST:<hn>
Listen Socket Status – Responds with a list of active Socket handles accepted for listen
socket identified by handle <hn>.
SST:<hn>
Single Socket Status – Responds with the status of a single socket identified by handle <hn>.
This is a subset of the RP4 Report.
SSND[%]:<hn>,
<sz>,<stream>
Socket Send – Send a byte stream of size <sz> to the socket identified by handle <hn>. ‘%’
flags auto flush socket.
SRCV:<hn>[,<max>]
Socket Receive – Receive a byte stream from the socket identified by handle <hn>. Accept
maximum <max> is not specified, all available bytes are retrieved.
GPNM:<hn>
Get Peer Name – Retrieve Peer Name (<IP>:<PORT>) of a remote connection to a TCP/UDP
socket specified by the socket handle <hn>.
SDMP:<hn>
Dump Socket Buffer – Dump all buffered data currently accumulated in a socket’s input
buffer. The socket remains open.
SFSH[%]:<hn>
Flush Socket’s Outbound Data – Flush (immediately send) accumulated data in a socket’s
outbound buffer. If the ‘%’, flush-and-acknowledge flag is specified, the modem will wait for
the peer to acknowledge receipt of the TCP packet.
[!]SCLS:<hn>
Close Socket – Close a UDP or TCP Socket. If the socket was the only open socket and the
stay online flag (‘!’) was not specified, the modem will terminate the Internet session and hang
up.
MCM
Modem Command – Sends an AT command to the modem.
FU
Firmware Update – Enters local monitor mode for firmware upload.
