13.8 Terminal mode
Terminal mode uses a simplified protocol. To
communicate with Drive address 02, the terminal
must be opened using the selection string. This is
done by transmitting the following message:
Drive
address
EOT 0 0 2 2 Cr
Ctrl-D Ctrl-M
The Drive responds with:
02>
The terminal remains in open communication with
this Drive until a different selection string is sent.
Interrogating the Drive
To interrogate the Drive, e.g. to find the value of
parameter Pr6, the message sent would be:
Pr
P6=
CR
Ctrl M
For bit parameter b24, the message would be:
Pr
P124= CR
Ctrl M
Sending commands to the Drive
To send a command to the Drive, the string is
composed of the same characters but with the new
value inserted after the = sign, as follows:
Pr Data field
P6=–035. 8 CR
Ctrl-M
Quick keystrokes
ESC
Resets the current command line, clearing it of
entered information
=
Requests a repeat of the data for the parameter last

>

number
<

number
