• transmit retry interval. When attempting additional transmit attempts as
specified with “transmit try count” above, it can be useful to additionally
specify how long to wait between attempts. This setting determines the time
period for retransmission attempts. The value is specified in 1/100ths of a
second, so that 100 means 1 second. The maximum value is 65000. The
default value is 100.
[tcpbind1a]
Four pre-written bindings, tcpbind1a, tcpbind1b, tcpbind2, and tcpbind3 are provided for
TCP/IP. When the protocol is set to passthrough, only one binding is used because only one
network socket is created (tcpbind2 and tcpbind3 are passthrough binds). When the
protocol is set to passthrough2, two complimentary bindings (one connect and one listen)
are used (tcpbind1a and tcpbind1b are complimentary) because a socket is created in each
direction.
• protocol. These examples use the TCP protocol, so the value of this entry is
tcp.
• type. The values in this entry can be either listen or connect. This specifies
whether the Ethernet Adapter will wait for a connection from another
computer or attempt to initiate the connection itself.
• ip address. This address is used in TCP protocol to specify the address to
which to connect. Connect must be selected for the IP address to be used.
• local tcp port. This port defines the TCP port number that the Ethernet
Adapter will wait for connections from other networked devices. Listen must
be selected for this port to be used.
• remote tcp port. This port specifies the TCP port numbers to connect to on
the remote computer. Connect is the type for this port.
• reopen after shutdown. If the type is listen, this value determines whether a
second connection will be accepted after the first connection terminates. If the
type is connect, this value determines whether another connection attempt
will be made if the first connection is closed by the remote computer.
• socket connect data. Data to be written to the connection once it is successful
is the socket connect data. The value is specified as a combination of a string
and ASCII values. For example, the default value is "Hello!" 0xd 0xa. (The
double-quote marks are a part of this value, unlike in some previous
examples.) The item in quotes and the ASCII values together make up the
data to be written. This example would cause 8 bytes to be written to the
socket; these are, in hexadecimal, 0x48 0x65 0x6c 0x6c 0x6f 0x21 0x0d 0x0a.
In fact, the data could have been specified on this line by using exactly those
eight hexadecimal values instead of as a combination of string and hex.
