Default TTL of outgoing data grams. This option is a limit on the period of time or
number of iterations or transmissions that a unit of data can experience before it
should be discarded. The time to live (TTL) is an 8-bit field in the Internet Protocol
(IP) header. It is the 9th octet of 20. Its value can be considered as an upper bound
on the time that an IP datagram can exist in an internet system. The TTL field is set
by the sender of the datagram, and reduced by every host on the route to its
destination. If the TTL field reaches zero before the datagram arrives at its
destination, then the datagram is discarded. This is used to avoid a situation in which
an undelivered datagram keeps circulating in the network. Valid range is 0-255. The
default value is 64.
Number of bytes of initial TCP window. This option is used to specify the number of
bytes in the initial TCP window. A TCP window specifies the amount of outstanding
(unacknowledged by the recipient) data a sender can send on a particular connection
before it gets an acknowledgement back from the receiver. The primary reason for
the window is congestion control. Valid range is 536 to 65535. The default value is
16384.
Default MSS of off-link connections. This parameter specifies the initial size of TCP
segment which would be sent. Note that the TCP protocol layer will negotiate this
parameter when the socket is opened. Valid range is 536 to 1460. The default value
is 536.
Total number of sockets (TCP and UDP) that are allowed. This option specifies the
maximum number of TCP and UDP sockets that can be created at one particular
time. Valid range is 1 to 8. The default value is 8.
This option is used to specify the time from the first character received on the
UART/serial port until TCP data is sent to the network. It allows the application to
buffer TCP data before writing to the TCP socket. Note: If 536 bytes of data are
received on the UART/serial port before the timeout, the TCP data will also be
removed from the UART and written to the TCP socket.
This option value represents the number of 100 millisecond time periods to wait. For
example, setting this option to 10 will make the application wait at least 1 second (10
* 100msec) before sending data on the IP network. Valid range is 1 to 100. The
default value is 3.
The UDP packet size. When the socket is opened as a UDP socket, this option
determines the UDP packet size. The valid range is 536 to 1460. The default value is
1460.
ICMP Ping Reply. This is a flag which indicates if the modem should reply to the
ICMP echo request which is used by ping. The valid values are 0 and 1. The default
value is 0 which means that no reply will be sent.
Restore configuration data from NV memory. The current working TCP/IP
configuration will be overwritten with the configuration stored in NV memory.
Save configuration data to NV memory. The current working TCP/IP configuration will
be written to NV memory.
