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
• error checks
• queries N8211A/N8212A for ID
• sets frequency on N8211A/N8212A to 2.5 GHz
• sets power on N8211A/N8212A to –5 dBm
• gets option letter from argument vector and checks for end of file (EOF)
The following programming examples are available on the N8211A/N8212A
Documentation CD-ROM as lanio.c and getopt.c.
