Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371G)
Optional parameter for HTTP method "Post".
Length: 0...127
Can be used to transfer a small amount of data. The content of this string will only
be sent if "hcContLen" = 0. The maximum length of "hcContent" is 127 bytes.
To transmit a larger amount of data "hcContLen" must be set to a non-zero value.
In this case the "hcContent" string will be ignored, and data transmission from the
client to the server is done with
Mandatory parameter for HTTP method "Post".
31
Length: 0...2 -1
The content length shall be set in the header of the HTTP "Post" request before the
data part is transferred.
If "hcContLen" = 0 then the data given in the "hcContent" string will be posted.
If "hcContLen" > 0 then the AT^SISW command will be used to send data from the
client to the server. In this case, "hcContLen" specifies the total amount of data to
be sent. The data can be sent in one or several parts. For each part, the
transmission is triggered by the URC "^SISW: x, 1", then the AT^SISW write
command can be executed. After the exact number of bytes are transferred via
the serial interface, the HTTP client will go from service state "Up" to service
state "Closing" (see parameters <srvState> and <srvState> for detail). Finally, the
URC. "^SISW: x, 2" indicates that all data have been transferred and the service
can be closed with AT^SISC.
The user agent string must be set by the application to identify the mobile. Usually
operation system and software version info is set with this browser identifier.
Length: 0...63
HTTP method specification: 0=GET, 1=POST, 2=HEAD.
Parameter for several HTTP settings.
Length: 0...127
The general format is 'key': <space> 'value' "\0d\0a".
Multiple settings can be given separated by "\0d\0a" sequences within the string.
Possible 'key' values are defined at HTTP/1.1 Standard RFC 2616.
This flag controls the redirection mechanism of the Multi-Tech Wireless EDGE
modem acting as an HTTP client (numeric).
If "hcRedir" = 0: No redirection.
If "hcRedir" = 1: The client automatically sends a new HTTP request if the server
answers with a redirect code (range 30x).
Default = 1
If set ("hcAuth" = 1), this flag determines that the HTTP client will automatically
answer on authentication requests from the server with the current "passwd" and
"user" parameter settings. If these parameters are not specified, the Multi-Tech
Wireless EDGE modem will terminate the HTTP connection and send an indication
to the TA.
Default = 1
Email sender address; i.e., "MAIL FROM" address (string).
Length: 6...256.
A valid address parameter consists of local part and domain name delimited by a
'@' character; e.g., "john.smith@somedomain.de".
Recipient address of the email; i.e., "RCPT TO" address (string).
Length: 6...256.
If multiple recipient addresses are to be supplied the comma character is used as
delimiter to separate individual address values; e.g.,
"john.smith@somedomain.de,tom.meier@somedomain.de".
CC recipient address of the email (string).
Length: 6...256.
If multiple CC recipient addresses are to be supplied, the comma character is used
as a delimiter to separate address values; e.g.,
"john.smith@somedomain.de,tom.meier@somedomain.de".
Subject content of the email (string).
Length: 0...256.
If no subject is supplied the email will be sent with an empty subject.
This parameter, if set, will be appended at the end of the email header section
(string).
Length: 0...256.
Hence, it serves as a generic header field parameter which allows the user to
provide any email header field. It is the user's responsibility to provide correct
header fields!
