The Monitor echoes back the parameter and status of the requested operation code.

1stbyte) STX: Start of Message

ASCII STX (02h)

2nd-3rdbytes) Result code

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.
