Multiple AT commands can be combined into one line. For example, AT&D2 and AT&K0 can be combined into one line AT&D2&K0. The Comet processes commands from left to right. The AT command that appears to the right might over-write the command to the left if they are trying to accomplish tasks or set modes that cannot coexist.
Modem Result Codes When you execute or try to execute an AT command, your modem sends a result code to let you know whether the command was executed. An OK result code means the AT command you sent was executed. If you receive an ERROR code, it means the command was invalid.
The ‘s’ is a number from 0 to 3 that represents the location in memory that the phone number is to be stored, and the ‘n’ is the phone number itself. Example: To store the number ‘1-714-555-1212’ in memory location ‘2’, type: AT&Z2=17145551212<Enter>...
