Remote control

The TI-73's remote control ability is "silent," which means that the calculator does not need to be put in a special mode. The remote control ability can be utilized any time the calculator is ready to accept a keypress.

Remote command:

The protocol used for sending a remote command is shown below.

Step | Direction | Packet
--- | --- | ---
1 |  |  |  | CMD
2 |  | ACK

The scancode of the key is sent in the last two bytes of the command. Scancodes are defined in the section ?? TI-73 guidebook or can be found in the TI83+ FLASH SDK (ti73.inc).

Example:

PC: | `07 87 9B 00` | Command: Key <B>
TI: | `74 56 9B 00` | Acknowledgement of command
