Subject: the connection when using external fax as a scanner
Status: RO

To clarify how to connect fax modem and fax machine when we use
external fax machine as a scanner. Because I don't understand how to do it
when I read "3.7 Using an external fax as a scanner" of mgetty.texi, I wrote.

Following is the connection in normal operation. I.e. Receiving fax
by Fax modem, sending fax by fax machine, make phone call, etc.

        +-------------------+  +----------------+

        |     (U1496E)      |  |     UX-5       |

In operation of using external fax as a scanner, the connection is follow.

        +-------------------+  +----------------+
        |    Fax Modem      |  |     Sharp      |
        |     (U1496E)      |  |     UX-5       |
        |                   |  |                |        +--------+
        |  Line     Phone   |  |  Line    Phone |        | Phone  |
        +-------------------+  +----------------+        +--------+
             |        |             |       |                 |
             +----------------------+       +-----------------+

The procedure of sending picture from UX-5 to Fax modem is follow.

1. put the paper to send on Fax machine.
2. pick up Phone hand set(Hang on)
3. push start button of Fax machine.
4. push data/voice button of Fax modem.

Of course you should set up mgetty for the terminal port of Fax modem as
follows.

/usr/local/sbin/mgetty -x 9 ttym0

As you know, "push data/voice button of Fax modem" can be substituted by
kill -USR1 <mgetty-pid>.
The fax machine which has dialing funtion does not need phone.
I need picking up phone hand set because UX-5 fax machine does not
recognize fax start by pushing start button of Fax machine.
If your fax machine has dialing funtion, you should dial any digit
without "2. pick up Phone hand set(Hang on)", and
"3. push start button of Fax machine." as described in mgetty.texi.

My environment
Computer	Panasonic (Matsushita Electric industry) BE workstation
Fax modem	ZyXEL U1496E V 6.01 M
Fax		Sharp UX-5, For personal use, No dialers i.e. needs phone.

Following is the log file when I receive a picture from fax machine.
