5. After you cd to the directory where the lanio.exe file is located, type in the following command at
the command prompt: lanio xxxxx “*IDN?”. For example:
C:\SocketIO\Lanio\Debug>lanio xxxxx “*IDN?” where the xxxxx is the hostname of your
signal generator. Use this format to output SCPI commands to the signal generator in a line by
line format from the command prompt.
6. Type exit at the command prompt to quit the program.
Programming Using main1() Function
The int main1() function will output a sequence of commands in a program format. If you want to
run a program using a sequence of commands then perform the following:
1. Enter the hostname of your signal generator in the openSocket function of the main1() function
of the lanio.cpp program.
2. Rename the lanio.cpp int main1() function to int main() and the original int main() function
to int main1().
3. Select Rebuild All from Build menu. Then select Execute Lanio.exe.
The program will run and display results similar to those shown in Figure 3-2.

Queries for Lan Using Sockets
lanio.c and getopt.c perform the following functions:
• establishes TCP/IP connection to port 5025
• resultant file descriptor is used to “talk” to the instrument using regular socket I/O mechanisms
• maps the desired hostname to an internal form
