00h: No Error.

01h: Unsupported operation with this monitor or unsupported operation under current condition.

This result code from the monitor is

encoded to ASCII characters.

Ex.) The byte data 01h is encoded to

ASCII character '0' and '1' (30h and 31h).

4th–5thbytes) OP code page: Operation code page.

These bytes indicate a replying item's OP code page.

This returned value from the monitor

is encoded to ASCII characters.
