Manual Conventions
<CR>
The notation “<CR> “ refers to the ASCII character for “carriage return” which is decimal 13 or hex D.
Every valid RIC40 command must be terminated by this character. In HyperTerminal the character is
sent when the “enter” key is pressed. Programs written in C for example, typically send this character
when “\r” is appended to the transmitted command string.
<LF>
The notation “<LF> “ refers to the ASCII character for “line feed” or “new line” which is decimal 10 or hex
A. Every string that is returned from the RIC40 will be terminated with this character. Actually, every
string that is returned from the RIC40 will be terminated with a <CR> then a <LF>. In HyperTerminal the
combined characters will cause the cursor to return to the beginning of the next line. Programs written in
C for example, can use this character (often “\n”) for parsing returned strings.
(string)
Characters within parenthesis are strings consisting of 7-bit ASCII characters and the string itself is the
argument for a command. The length of the string is clarified in the discussion of the command and the
two parenthesis are not included in the transmission of the command string.
