Command Function Parameters/Description<br />
STCP:, Socket TCP<br />
Socket Interface<br />
Opens and connects a TCP socket. If iChip is not<br />
[,]<br />
online, it is connected. The responding system is<br />
assumed to be a server listening on the specified<br />
socket. Returns a handle to the socket.<br />
SUDP:<br />
Socket UDP Opens, connects, and optionally binds a UDP<br />
,<br />
socket. If iChip is not online, it is connected.<br />
[,]<br />
Returns a handle to the socket.<br />
LTCP:<br />
Listening socket Opens a TCP listening socket on . Allows a<br />
,<br />
maximum of concurrent connections.<br />
Returns a handle to the socket. Up to two listening<br />
sockets are supported.<br />
LSST: Listening socket Returns a list of active socket handles accepted for<br />
status<br />
a listening socket identified by handle .<br />
SST: Single socket status Returns status of a single socket identified by<br />
handle . A subset of RP4 report.<br />
SCS: Socket connection Returns status of a single socket identified by<br />
status<br />
handle . A subset of RP4 report. Does not<br />
report number of buffered characters.<br />
SSND[%]:<br />
Socket send Sends a byte stream of size to the socket<br />
,:<br />
identified by handle . The % flag indicates<br />
automatic socket flush.<br />
SRCV: Socket receive Receives a byte stream from the socket identified<br />
[,]<br />
by handle . Accepts up to bytes. If<br />
is not specified, all available bytes are<br />
retrieved.<br />
GPNM: Get peer name Retrieves peer name (:) of a remote<br />
connection to the TCP/UDP socket specified by<br />
socket handle .<br />
SDMP: Dump socket buffer Dumps all buffered data currently accumulated in a<br />
socket‘s input buffer. The socket remains open.<br />
SFSH[%]: Flush socket‘s Flushes (sends immediately) data accumulated in a<br />
outbound data socket‘s outbound buffer. If the flush-andacknowledge<br />
flag (!) is specified, iChip waits for<br />
peer to acknowledge receipt of the TCP packet.<br />
[!]SCLS: Close socket Closes a TCP/UDP socket. If that socket is the only<br />
socket open and the stay online flag (!) is not<br />
specified, iChip terminates the Internet session and<br />
goes offline.<br />
SSL: SSL3/TLS1 socket Negotiates an SSL3/TLS1 connection over an<br />
connection active TCP socket.<br />
