I'm trying to configure a Cisco 1941 to use a cell network with a EHWIC-3G-HSPA+7 card
It auto generates the following command:
chat-script hspa-R7 "" "AT!SCACT=1,1" TIMEOUT 60 "OK"
Most cell configs I've seen use a chat-script similar to the following:
chat-script xxx "" "ATDT*98*1#" TIMEOUT 30 CONNECT
a. What is the difference between the two AT commands?
b. What is the purpose of 1,1 rather than just 1? I know the profile is selected using the 1, but I can't find any command reference that describes the use of the comma in first example.
generally speaking the chat script is provider specific and depends on specific technology flavor.
About your specific question on the chat-script automatically generated.
It is present also in configuration guide for the module
Looking for AT messages command reference I have found the following:
AT!SCACT=<state>[,<pid>] is used to set the state of the identified profile (<pid>). If no <pid> is specified, profile 1 is updated.
on page 40 of the following pdf document
The document provides also the links to the standards for AT commands that you can find here:
the document is very long in its last version 389 pages word document.
You can try the proposed chat script that is used for example by T-mobile in Germany see
Hope to help
