U.S. Robotics I-modem Command Reference
Analog Synchronous Applications • Page 16-17
There are two methods of autodialing a stored telephone number: You can have the I-
modem dial the stored number either when it receives the Data Terminal Ready (DTR)
signal from your computer or at power-on/reset.
1. Store a telephone number to memory position 0 using the AT&Z0=n command. For
example, to store [phone], and tone dial, type:
AT&Z0=T18475551111 <Enter>
2. Follow step a or b, depending on the dialing method you choose.
a. To have the I-modem dial when it receives the DTR signal from your computer, type:
ATS13.3=1&W <Enter>
b. To have the I-modem dial when you power it on or reset it, type:
ATS13.4=1&W <Enter>
3. Make sure DIP switch 1 is set to ON to load settings from NVRAM.
Hanging Up
The I-modem remains online until the remote device disconnects, your software causes
the DTE to drop the Data Terminal Ready signal (DTR), or you power off the I-modem.
When one of these events occurs, the I-modem returns to asynchronous Command mode
