Programming the HP 16500B
To write programs that open the command parser socket
To write programs that open the command parser
socket
•
If you are programming in C, open the HP 16500B command parser
socket and send programming commands to it.
The HP 16500B command parser socket port identification number is 5025.
Connection to the command parser socket is, by definition, a control user
connection. Because only one control user connection is allowed, you will
not be able to open the command parser socket if someone else is accessing
the HP 16500B's file system as the control user.
Example
The following C program opens a SOCKET and sends the *IDN query
command to request the instrument's identity.
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
typedef struct sockaddr_in tdSOCKET_ADDR;
#define PARSER_PORT
#define SERV_HOST_ADDR
#define PARSER_BUFFER_SIZE
char
main ()
{
5-12
receiveBuffer[PARSER_BUFFER_SIZE],
*cmdString = { "*IDN?\r\n" };
int
sockfd, port;
tdSOCKET_ADDR
serv_addr;
char
*addr;
/* Initialize a server socket */
port = PARSER_PORT;
addr = SERV_HOST_ADDR ;
serv_addr.sin_family = AF_INET;
serv_addr.sin_addr.s_addr = inet_addr ( addr );
