Outgoing Data Call
Dialing Through the System Modem Pool
A PC involved in this type of call must be running a communications software 
program. Before making this call, verify that the communication parameters of your 
PC or terminal match those of the device that your are calling.
To place the RPCI-DI into the command mode while keeping the modem in the 
communications mode, Toshiba recommends that the RPCI-DI escape sequence be 
changed from +++
 to some other sequence before beginning. For example: Using the 
ATS2 command, send ATS2=36
 to the RPCI-DI to change its escape sequence to 
$$$. Store these commands in the PC communication software modem initialization 
sequence - this sets the RPCI-DI escape sequence each time the communication 
software is run. 
äTo verify communications from your PC or terminal
äType AT, and press 
Enter on your PC or 
terminal.Wait for the following to display on your PC or 
terminal screen.
This display verifies that communications exist 
between your PC or terminal and your data telephone.
NoteAT commands must be typed as capital letters 
(use caps lock), and they appear on your PC or 
terminal screen as you type them.
