Remote Port Number (Command, Results Storage Area): Specify the
remote TCP port number with this command. If all zeroes are set, no remote
TCP port number is specified. If any other value is set, it specifies the TCP port
number of the remote node. The TCP port number of the connected remote
node will be stored in the results storage area.
Response code Description
0000 Normal
1100 TCP socket number is out of range.
Remote IP address is 0.
1101 The memory area code for the results storage area is out of
range.
1103 Non-zero bit address is specified for the results storage area.
220F The specified socket (connection) is already open or is
currently being opened.
Response code Description
0000 Normal
003E Cannot secure the internal buffer. (ENOBUFS)
0080 An open request timeout error occurred.

Parameters TCP Socket Number (Command): Specify the TCP socket number to be
opened as two bytes between 1 and 4.
Results Storage Area (Command): The words 0 to 255 and 256 to 511 of the
memory area, words 0 to 6143 of the data memory, and words 0 to 6143 (each
bank) of the expansion data memory can be used. However, do not designate
the special auxiliary area. Refer to 11-1-4 Memory Area Designations. When a
bank that does not have expansion data memory is designated, the Results
Storage Area Error Flag will turn ON.
Local TCP Port Number (Command, Results Storage Area): The local TCP
port number is specified as two bytes. An available TCP port number is automat-
ically assigned if 0 is specified. The TCP port number allocated to the open
socket is stored in the results storage area.
Note Do not make other port specifications if you specify the local TCP port number.
Making other specifications may cause transmissions to collide on the port.
