More Information

Dip switches 1 and 2 must be ON (DOWN) for the Modem. These are supposed to be the defaults, but we've found that some of the documentation diagrams on the modem are incorrect. These two switches enable AT commands and Loading data from NVRAM.

Here is a chat script that has worked:

send at*D0=1
send at*V2=5
send at*p=3
send atd xxxxxx ----PID#
