When trying to send an unsupported command, the ostc will simply ignore the command. Instead of echoing the command byte back, the ostc will immediately send the ready byte, to indicate it's ready to receive the next command. We can use this to detect unsupported commands, because the ready byte is a reserved value and guaranteed to never be a valid command byte. Normally we don't send invalid commands. But newer firmware version can always introduce new commands to support new features. To maintain backwards compatibility with older firmware versions, it's important to be able to detect unsupported commands and provide a fallback.
