program running on host first sens a few of dummy bytes to the terminal and delay for about

500 mini-second to remotely wake up the unit. Then the program can send out a data pack of a

remote PTFileManager that matches the MULTI protocol to the terminal and instruct the

terminal for certain process.

For instance, the terminal will automatically execute the system routine to upload a file after

receiving the valid “File upload” PTFileManager. Meanwhile the program running on the host

should follow the control flow of MULTI protocol and process to receive the data.
