Chapter 3 – Fax Class 2 Commands

Set Current Time and Date, AT+FTD

The AT+FTD command is used to set the current date and time. The current time and date will be tracked automatically by the modem once the time and date are set. However, these boards do not have a real time clock. So, the accuracy of the time and date is not guaranteed. It is recommended that the current time and date be set before each FAX transmit session.

The syntax of the command is:

AT+FTD=<year>, <month>, <hour>, <minute>, <second>, <zone>, <dtsdelta> The arguments to this command are:

<year>

The current year (UTC zone). Range: 1970 to 65535

<month>

The current month number (UTC zone). Range: 1 to 12.

 

January is 1.

<day>

The current day of the month. Range: 1 to 31.

<hour>

The current hour in military time (UTC zone). Range: 0

 

to 23.

<minute>

The current minute (UTC zone). Range 0 to 59.

<second>

The current second (UTC zone). Range 0 to 59.

<zone>

The number of seconds east (positive) or west

 

(negative) that the local time zone is from Greenwich.

 

Range: -43200 to 43200.

<dtsdelta>

Zero if daylight savings time is not in effect at the current

 

time. Otherwise, the number of minutes to add to the

 

time. Range 0 to 255.

The current local time is calculated from the UTX (Universal Coordinated Time, i.e., GMT) time specified in this command, plus the <zone> offset, plus the <dtsdelta> offset, plus the number of seconds accumulated by the board since the command was executed.

Page Header Generation, AT+FPH

The AT+FPH command is used to enable automatic generation of a FAX page header.

There are four legal formats for the syntax of this command: AT+FPH=mode, “left”(string is left justified) AT+FPH=mode, “left’middle’ right” AT+FPH=mode, “left ’right”

The arguments to this command are:

mode

The mode argument controls generation of the page header. A mode of 0 disables page header generation. A mode of 1 enables page header generation and the page header is prepended to the FAX page data. A mode of 2 enables page header generation and the page header is overlaid on the first few lines of the FAX page data. string

The string defines the page header itself. Only ASCII printable characters are allowed in the string (0x20 through 0x7e). Escape sequences that are introduced with the percent (%) character are allowed. The string can be partitioned into one, two, or three parts by using single-quote characters ( ‘) in the command expression.
