The sent & received commands end with a line feed. The corresponding
binary code is 0x0d and 0x0a.
For example: send the command of getting series number *IDN?
7 characters *IDN?/0x0d/0x0a should be sent practically.
In the command, it has returned value with '?', otherwise, it is control
statement.
The standard SOCKET communication could be used in programming. Pay
attention in some large data volume transmission, such as TRACe?. Get the
current wave data, return to float type data of 421 points, and it is 1692
characters in total with file header #42004 and end-of-file 0x0d 0x0a.
Generally MTU (maximum transmission unit) is set as 1500 charaters in
network transmission. At the moment the data would be divided into 2
packs. Programmers should consider the problem of combining packs.
