I’m pretty certain, though the memory is deep in the mists of time, that I’ve seen it return zero before, in the situation of massive data transfers where the other end was not keeping up. From memory, in that case, the remote TCP stack buffers had filled up, the stack had notified the local end … Read more
Please be aware of this note from the mail documentation: Note: It is worth noting that the mail() function is not suitable for larger volumes of email in a loop. This function opens and closes an SMTP socket for each email, which is not very efficient. For the sending of large amounts of email, see … Read more
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); IPAddress serverAddr = IPAddress.Parse(“192.168.2.255”); IPEndPoint endPoint = new IPEndPoint(serverAddr, 11000); string text = “Hello”; byte[] send_buffer = Encoding.ASCII.GetBytes(text ); sock.SendTo(send_buffer , endPoint);
The thing that is missing in above description is, in Unix, system calls might get interrupted with signals. That’s exactly the reason blocking send(2) might return a short count.
This is a really old post but there has not been an answer here, I was looking for something exactly like this, and I had spend 6 hours going through Stackoverflow, and ended up just reading all the C documentation because it was more useful. #you will need the win32 libraries for this snippet of … Read more
I’ve written a sample application to test the answer provided. Unfortunately it doesn’t work for me, so I think this question is not completely answered.
This worked for me: echo “<b>HTML Message goes here</b>” | mail -s “$(echo -e “This is the subject\nContent-Type: text/html”)” [email protected]

Let me know if it worked, thank you! 2020 Jun 13 Edit: A Discord.js update requires … Read more

General note about your handling of AT commands. No, no, no! This way of doing it will never work reliably. You MUST wait for the > character to be received before sending “text to send”. Or actually it is not just the > character, it is four characters. Quote from 3GPP specification 27.005: the TA … Read more
