Fax Software
The fax capabilities of the ALX modem are accessed through an external fax software program
only (not by commands sent directly by the user to the modem). To send and receive fax
messages, follow the instructions provided with the fax software you are using. A partial list of
fax software programs that are compatible with the ALX appears below:
FaxTalk and FaxTalk Plus …
Thought Communications, Inc.
MTEZ and ExpressFax …….
MagicSoft, Inc.
WINFAX ……………………..
Delrina Technology Inc.
Note:
During fax communications, the TIA/EIA status screen on the ALX front panel will
switch frequently between the “IDLE” message and displays showing various data rates. This is
normal. The higher rate displayed is the actual fax transmission rate; the lower rate is the fax
protocol rate, which is used for sending signals such as “end-of-page” between the two facsimile
devices.
Fax Class
When selecting or installing fax software, you may be required to choose the interface mode (fax
class) to be used by the software and the ALX. You must select a fax class (1 or 2) that is
supported by both the software program and the modem. If the software and the modem both
support both fax classes, you can select either one. The fax class defines the protocol used for
communication between the modem and the computer it is connected to. The fax class used is
generally transparent to the user.
The Hayes command
AT +FCLASS=?
can be used to find out if a particular modem supports
fax communication (and if so, which class or classes). If you enter this command (in Hayes
mode only), the modem will respond by sending one or more numbers to the computer’s display,
as follows:
Response
Meaning
0
No fax capability (data modes only)
0, 1
Supports fax class 1
0, 1, 2
Supports fax classes 1 and 2
Flow Control
If your fax software manual instructs you to configure the modem for software flow control,
enter the command
AT \Q3,3
. If the manual specifies hardware flow control, enter the command
AT \Q1,1
. If received fax messages show incomplete characters or incomplete graphic data
across the page (missing scan lines), try the alternate setting (
AT \Q1,1
or
AT \Q3,3
).
