If the command length is greater than 266 characters, divide the frame.
1. Divide the frame so that each frame consists of up to 266 characters.
2. Append a terminator (∗CR) only to the last frame (frame n). Append a delimi-
ter (CR) at the end of the other frames.

are necessary for the first frame (frame 1). If one of these is missing, a com-
mand input error occurs. The write data can be omitted.
