Consult how TCP Client sends a carriage return-CodePudding

After consult the TCP Client sends a string to send a return
Now I sent the sender string PRESET - a 1 there is space behind (1)
The receiver received: 50 52 45 53 45 54 2 d 61 20 and 20
This piece of string after I also need a 0 d program instructions to control the receiving end, then the 0 d in sending the how to write, to make the receiver received 0 d
Is the receiver to receive: 50 52 45 53 45 to 54 20 61 20 and 20 0 d to 2 d controlled
Thanks to the great god taught, novice don't understand TCP

This is not what I want to answer,
I ask is when I want to send in the PRESET - what a 1 after add
To make the receiver received
53 45 to 54 50 52 45 20 61 31 20 0 2 d d

It's wrong to both used,

Estimation is your agreement didn't analysis, clearly transmit data of enter 0 d does not necessarily mean, how to parse the number depends on the receiving end

The software testing is to use TCP Client ah, I also not actually must back to the car, the purpose of receiving end when I send the end of the string can receive 0 d

Sending code to look at you

Now I sent the sender string PRESET - a 1 there is space behind (1)
The receiver received:
53 45 50 52 45 54 2 d 61 20 31 20
But I need receive the receiving end of:
53 45 50 52 45 54 20 61 31 20 0 2 d d
To perform a controlled, the problem is how to add 0 d in the back to him

CodePudding user response:

I'm talking about the code, you are talking about the software, not a channel, send a carriage return
Char * SendData publishes the event="https://bbs.csdn.net/topics/PRESET - a 1/n";
Send (SocketID, (char *) & amp; SendData publishes the event, strlen (SendData publishes the event) + 1, 0);
Solved, not write code, you can't discuss
