3.4 Upload/Download by ESC Command
The way to upload/download by Kermit server described in section 3.2 will need the operator to set the
terminal to Kermit server mode by selecting user command “3.COM” in User mode or calling system
function in application program.
The hardware and software of terminal is designed that the unit can be woken up (turned on) by input from
the serial port. Besides, the terminal can also be instructed to process data communication by remote ESC
commands through built-in MULTI communication protocol. (Please refer to PT630D Technical Binder
for
detail information)
After linking the terminal to a PC/host through RS232 interface, a communication program running on host
first sends a few of dummy bytes to the terminal and delays for about 500 mini-second to remotely wake up
the unit. Then the program can send out a data pack of a remote ESC command 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” ESC command. Meanwhile the program running on the host should follow the control
flow of MULTI protocol and process to receive the data.
For detailed description of each ESC command and protocol, please see the PT630D Programming
Reference Manual.
