Basic NNTP Protocol
Directly from RFC977 2.2. Character Codes
- "Commands and replies are 7-bit ASCII. When transmitted in octets, the MSB is 0."
As noted below, commands are not case sensitive.
Directly from RFC977 2.3. Commands
- Commands consist of a command word, which in some cases may be followed by a parameter.
- Commands and command parameters are not case sensitive. That is, a command or parameter word may be upper case, lower case, or any mixture of upper and lower case.
- Each command line must be terminated by a CR-LF (Carriage Return-Line Feed) pair.
- Command lines shall not exceed 512 characters in length, counting all characters including spaces, separators, punctuation, and the trailing CR-LF (thus there are 510 characters maximum allowed for the command and its parameters). There is no provision for continuation command lines.
- Commands with parameters must separate the parameters from each other and from the command by one or more space or tab characters.
- Command lines must be complete with all required parameters, and may not contain more than one command.
