ASCII '0''1' (30h, 31h): Unsupported operation with this monitor or unsupported operation under

current condition.

4th-5thbytes) OP code page: Echoes back the Operation code page for confirmation.

Reply data from the monitor is encoded to ASCII characters.

Ex.) OP code page 02h ->

OP code page = ASCII '0' and '2' (30h and 32h)

Refer to Operation code table.

6th-7thbytes) OP code: Echoes back the Operation code for confirmation. Reply data from the monitor is encoded to ASCII characters.
