/*!
|
|
* Queue an AT command for execution. The command contents are given
|
|
* in cmd. Once the command executes, the callback function given by
|
|
* func is called with user provided data in user_data.
|
|
*
|
|
* Returns an id of the queued command which can be canceled using
|
|
* g_at_chat_cancel. If an error occurred, an id of 0 is returned.
|
|
*
|
|
* This function can be used in three ways:
|
|
* - Send a simple command such as g_at_chat_send(p, "AT+CGMI?", ...
|
|
*
|
|
* - Send a compound command: g_at_chat_send(p, "AT+CMD1;+CMD2", ...
|
|
*
|
|
* - Send a command requiring a prompt. The command up to '\r' is sent
|
|
* after which time a '> ' prompt is expected from the modem. Further
|
|
* contents of the command are sent until a '\r' or end of string is
|
|
* encountered. If end of string is encountered, the Ctrl-Z character
|
|
* is sent automatically. There is no need to include the Ctrl-Z
|
|
* by the caller.
|
|
*
|
|
* The valid_resp field can be used to send an array of strings which will
|
|
* be accepted as a valid response for this command. This is treated as a
|
|
* simple prefix match. If a response line comes in from the modem and it
|
|
* does not match any of the prefixes in valid_resp, it is treated as an
|
|
* unsolicited notification. If valid_resp is NULL, then all response
|
|
* lines after command submission and final response line are treated as
|
|
* part of the command response. This can be used to get around broken
|
|
* modems which send unsolicited notifications during command processing.
