Chapter 3 – Fax Class 2 Commands
Multi-Tech Systems, Inc. SocketModem MT5634SMIxx Reference Guide (S000263C) 92
An escape sequence is a “%” followed by an optional width, which may include a
leading left-justification signifier, and then by the escape character itself. It is of the
form %[numbers][-]character. The dash (“-“) denotes left justification. When the
dash is absent, right justification is used. If the width specification starts with a zero,
then, when the escape sequence is expanded, the value will be left-padded with
zeroes. Otherwise, it will be left-padded with spaces.
The following escapes are recognized:
%d (or %D ) The day of the month as a decimal number (range 01 to 31).
%h (or %H ) The hour as a decimal number using a 24-hour clock (range 00 to 23).
%i (or %I ) The hour as a decimal number using a 12-hour clock (range 01 to 12).
%j (or %J) The day of the year as a decimal number (range 001 to 366).
%m The month as a decimal number (range 01 to 12).
%M The minute as a decimal number (two digits).
%p Either ‘am’ or ‘pm’ according to the given time value, or the
corresponding strings.
%P The current page number of the FAX being sent, as computed by the
padding.
%r (or %R) The ID of the remote FAX machine. Leading and trailing blanks are
stripped. A print-style field width specifier such as %20r or %-20r can
be used to print this always in a fixed width field.
%s (or %S) The second as a decimal number (two digits).
%t (or %T) The ID of the transmitting FAX machine. Leading and trailing blanks
are stripped. A print-style field width specifier such as %20t or%-20t
can be used to print this always in a fixed width field.
%y The year as a decimal number without a century.
%Y The year as a decimal number including the century.
%% A literal ‘%’ character.
If the string contains single quotes, it will be partitioned into left, and also possibly,
middle and right parts.
left This portion of the header will be left justified.
middle This portion of the header will be centered.
right This portion of the header will be right justified.
Percent-introduced escapes are processed as above.
Miscellaneous Parameters
Buffer Size, +FBS (Class 2.1 only)
Read syntax: +FBS?
modem response syntax: <bs>,<xoft>,<xont>,<bc>, where
<bs> = total buffer size,
)
<xoft> = XOFF threshold,
<xont> = XON threshold,
<bc> = current buffer byte count
This parameter allows the host to determine the characteristics of the modem’s data
buffer. Flow control is mandatory; buffers are needed for flow control. Use of the
reported values would allow a host to transfer data without provoking XOFF.
