RAW TCP/UDP Socket Support – Setup Commands

Command Syntax socket listlisten [-s] [-d]

Description -s : When the socket-only option is specified, it displays the TCP server socket

handle, local port, backlog and TCP listen socket handles.

-d : When the socket-detail option is specified, it displays all socket-only option

information along with the TCP listen socket's Local IP address, Local Port,

Remote IP address, Remote Port, etc.

The displayed handles are limited to backlog specified in "socket tcplisten <listen-

port> <backlog>" command.1. If no options are specified, it displays all information

as listed in -d option.

The handles are displayed in ascending order with respect to their connect-times.

Default Value

NULL

Success

Error 1. Invalid argument

Type socket listlisten ? for more information

2. Multiple matches

listall listlisten

Command Syntax socket listall [-s] [-d]

Description -s : When the socket-only option is specified, it displays information about all the

active sockets opened by the host device.

Command Syntax socket send <[-s <size>] [-d <delimiter>]>

[-m <MTU>] <socket_handle>

Description

Validates the specified socket handle (corresponds to TCP or UDP socket) and

waits for the data stream. .

If delim parameter (char) is specified, the host can enter the data and the IP Module

flushes the data as soon as it detects the specified delimiter character.

If the size parameter is specified, the IP Module waits for the specified size bytes to

send to the socket's output buffer.

If the optional mtu parameter is not specified, the data is flushed immediately.

If the mtu parameter is specified, the data stream is flushed in integral multiples of

specified value (Maximum value being MTU size).

Notes:

1. Either delim or size should be specified by the host device.

2. If the mtu pktlen (packet length) is given more than the data stream sent, it

waits until

a.) it reaches the mtu size or

b.) the delim matches or

c.) the size specified by the user to flush the socket buffer is reached.

Default Value

Success

Error 1. Invalid Socket handle

2. Option missing

3. Connection refused

Send: Connection refused

0-bytes sent.
