| Examples: | Command names are sent over the ssh pipe as plain text, followed by a ''single character'' linebreak. This is important on systems that automatically use a two character line-break, such as CR+LF on Windows: if there is extra whitespace on the end of the command (in the case of windows, there will be an extra CR at the end), it will not be recognized. |

This page is an incomplete stub. Please Command names are sent over the ssh pipe as plain text, followed by a single character linebreak. This is important on systems that automatically use a two character line-break, such as CR+LF on Windows: if there is extra whitespace on the end of the command (in the case of windows, there will be an extra CR at the end), it will not be recognized.
Arguments are sent as [argname] [value length]\n, followed by the value. Responses are [response length]\n, followed by the response.
