Frame Division
Divided the command into frames as shown below if the command is longer than 271 characters.
Frame Division
1. Divide the command so that each frame is 271 characters or less.
2. Attach a terminator (*CR) to the last frame (frame n). Attach a delimiter (CR) to all other frames.
3. The first frame (frame 1) must contain the command code, data code specification, Read/Write Head
and channel specifications, and the start address. If any of these are missing, a command input error
will occur. The write data does not have to be contained in the first frame.
4. Divide the command so that no frame contains “AA*CR” or “XZ*CR”.
