What to look for when receiving data via ASCII?

Answers

Top answer

It all depends on identifying the final character in the message.

After the expiration of the inter-catastrophe (The telegram has neither a fixed length nor an end character, so the end of the message is recognized by a break on the line)
After receiving the end character (The end of the message is defined by the end character set in advance)
After receiving a certain number of characters (The message is terminated after the number of characters is received. If the message does not end in one transmission, the data is lost and cannot be linked)
