[ 5 ] Connect to TCP/IP Communications Pathway
Use the extension library SOCKET.FN3. Connecting to the TCP/IP communications pathway
requires the following settings (specified in [ 2 ]):
• IP address
• Subnet mask
• Default gateway
There are two ways to specify these parameters.
(a) Use the system settings with the extension library
SOCKET.FN3. Refer to Section 18.6,
"Socket Library (SOCKET.FN3)."
Given below is an example using
SOCKET.FN3.
call "socket.fn3" .fcTCnnSys interface% ’Connect to communications pathway
’(SOCKET.FN3 function #41)
’Use the returned value of [3] in
’interface%.
(b) Use user-defined values provided by the application with the extension library
SOCKET.FN3. Refer to Section 18.6, "Socket Library (SOCKET.FN3)."
Given below is an example using
SOCKET.FN3.
my.addr$ = "192.168.0.125" ’IP address of the BHT
subnetmask$ = "255.255.255.0" ’Subnet mask
gateway$ = "0.0.0.0" ’Default gateway
call "socket.fn3" .fcTCnnUsr interface%, my.addr$, subnetmask$, gateway$
’Connect to communications pathway
’(SOCKET.FN3 function #42)
’Use the returned value of [3] in
’interface%.
[ 6 ] Transfer Data or File via Socket Interface
To transfer data via the socket interface, use the extension library SOCKET.FN3. Refer to
Section 18.4, "Socket API" and Section 18.6, "Socket Library (SOCKET.FN3)."
To transfer file via the socket interface, refer to Section 18.5.3, "Using FTP Client."
