Setting Up for Remote Access
Remote Access allows authorized Users to remotely issue AT commands from a Modemulator to another
Modemulator that is in Remote Command Mode. The AT commands that are supported by Remote
Command Mode are identified with a '*' in the Command Reference chapter of this document.
Remote Command Mode is enabled on a per-connection basis at the originating Modemulator by issuing
the
{R1 command
to schedule Remote Command Mode for the next connection with an answering
Modemulator. The Remote Command Mode scheduling will automatically clear upon disconnect.
Here are the steps for locally setting up Remote Access:
1. Connect a computer serial port to the originating Modemulator Terminal port with a serial cable. Run a
terminal application on the computer to facilitate sending commands into the Modemulator.
2. Issue the
{R1 command
Example:
AT{R1
USR recommends not sending &W to the Modemulator while {R1 is set to prevent Remote
Command Mode from being enabled following every reset.
Starting A Remote Access Session
1. Dial the remote Modemulator that you want to manage. Use any form of the D command (ATD, ATD:
or ATDL) to initiate a connection to the remote Modemulator that you want to manage.
Example:
ATD18005551234
If the originating Modemulator detects that the phone number being dialed is a PSTN number and
if a dial-up modem is connected to the Modemulator "Modem" port, Modemulator will attempt a
dial-up connection. Regardless if that attempt succeeds or not, {R1 will automatically revert to
{R0.
Password Prompting Is Disabled
If Password Prompting is disabled in the answering Modemulator, the originating Modemulator will
display a CONNECT message and enter Remote Command mode. The answering Modemulator will then
accept and process any AT commands identified with a '*' in the
document.
