command
*1: "SP" is space
*2: The command argument n depends on the number of non-procedural command
arguments.
 Return Value
Err. No. Error Message

 Precautions
The length of the string of the no-stepping command that can be sent is 127 bytes (not
including the delimiter).
Set the parameters of cmd_name and cmd_arg{*} so that the length of the string of the
no-procedure command to be sent does not exceed 127 bytes.
 Example
The following example shows how to send the measurement command "MEASURE" to
the Vision Sensor
cmd_name := "MEASURE";
cmd_arg{1} := "";
cmd_arg{2} := "";
cmd_arg{3} := "";
cmd_arg{4} := "";
cmd_arg{5} := "";
cmd_arg_num := 0;
fhrunsendcmd fh_socket, cmd_name, cmd_arg, cmd_arg_num, err_no;
