PCTEL V.90/K56Flex Series AT Command Guide
A command line is a string of characters sent from a DTE to the modem
(DCE) while the modem is in a command state. A command line has a
prefix, a body, and a terminator. Each command line (with the exception
of the A/ command) must begin with the character sequence AT and must be
terminated by a carriage return. Commands entered in upper case or
lower case are accepted, but both the A and T must be of the same case,
i.e., “AT or “at. The default terminator is the ENTER key character.
Characters that precede the AT prefix are ignored.
The command line interpretation begins upon receipt of the ENTER key character. Characters within the command line are parsed as commands with associated parameter values. The basic commands consist of single ASCII characters, or single characters proceeded by a prefix character (e.g., “&” or “+”), followed by a decimal parameter. Missing decimal parameters are evaluated as 0. When the modem has established a connection and has entered on-line data mode, it is possible to break into the data transmission in order to issue further commands to the modem in an on-line command mode.
