[ 6 ] 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%.
[ 7 ] 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."
