AT commands (via USB Virtual COM)
Use any RS232 terminal application or RS232
interfaced hardware to send the AT text commands to
the RSLogger device in Virtual COM mode set to AT
commands interface mode (VIRTUALCOMMODE=4).
Each command to get accepted needs to carry the
actual device password in the command syntax. Each
command executed will result in <END password>
footer returned by RSLogger, indicating the command
execution or data flow end.
Free Termite terminal (by Compu Serve) in the
example shown on the left.
