Roll-Up II 48

2. Send the command one character at a time. The Controller will respond by echoing

each character. Waiting for the character to be echoed will ensure that the

Controller has received the character and is waiting for the next one.

3. Once the command is complete, send a <CR> or <ESC> (hex 1B) to exit command

mode.

4. If you send a <CR>, go into a loop and grab one byte at a time until a > prompt is

received. Then continue sending commands as described in step 2.
