.SH DESCRIPTION
|
|
.I Telco
|
|
is a file server that provides a network interface to
|
|
Hayes telephone dialers.
|
|
The interface is the same as that provided by
|
|
.IR ip (3)
|
|
and can be used by any program that makes network connections using
|
|
.IR dial (2).
|
|
The network addresses used by
|
|
.I telco
|
|
are telephone
|
|
numbers.
|
|
.PP
|
|
The options are
|
|
.TP
|
|
.B -p
|
|
use pulse dialing
|
|
.TP
|
|
.B -v
|
|
verbose: write to the log file all communications with
|
|
the dialer.
|
|
.TP
|
|
.B -i
|
|
specify a
|
|
.I source-id
|
|
to be used during FAX transfers
|
|
.PP
|
|
Some control of outgoing calls can be encoded
|
|
in the address.
|
|
Normally, addresses are of the form
|
|
.IB telco ! number\f1,
|
|
where
|
|
.I number
|
|
is a decimal telephone number.
|
|
However, commas in the telephone number can be used to insert
|
|
pauses in the dialing process.
|
|
Dialing options can be added to the end of the address, separated
|
|
by
|
|
.BR ! 's.
|
|
The dialing options are
|
|
.TF baudrate
|
|
.TP
|
|
.B compress
|
|
turn on compression (default off)
|
|
.TP
|
|
.I baudrate
|
|
a decimal number representing the highest baud
|
|
rate with which to make the call
|
|
.TP
|
|
.B fax
|
|
to make a Class 2 facsimile call (used by programs such as
|
|
.IR faxsend )
|
|
.PD
|
|
.PP
|
|
.I Telco
|
|
also answers incoming calls.
|
|
Upon receiving a facsimile call,
|
|
.I telco
|
|
starts the script
|
|
.BR /rc/bin/service/telcofax .
|
|
For data calls it starts
|
|
.BR /rc/bin/service/telcodata .
|
|
Each is started with the network connection as both standard
|
|
input and standard output and with two arguments,
|
|
the file name of the network connection, e.g.,
|
|
.BR /net/telco/0/data ,
|
|
and the type of modem.
|
|
Currently, the only modem types supported are:
|
|
.TF ATT14400
|
|
.TP
|
|
.B MT1432
|
|
Multitech's 14400 baud modem
|
|
.TP
|
|
.B MT2834
|
|
Multitech's 28800 baud modem
|
|
.TP
|
|
.B ATT14400
|
|
the 14400 baud modem in Safaris
|
|
.TP
|
|
.B VOCAL
|
|
the 14400 baud Vocal modem
|
|
.PD
|
|
.PP
|
|
All other modems are assumed to be compatible with the standard
|
|
Hayes command subset.
|
|
.PP
|
|
.I Faxreceive
|
|
is normally started by
|
|
.BR /rc/bin/service/telcofax .
|
|
It reads and spools a CCITT Group 3 (G3) encoded FAX, and then starts the
|
|
script
|
|
.BR /sys/lib/fax/receiverc ,
|
|
passing it four arguments: the spool file name,
|
|
.B Y
|
|
(for success) or
|
|
.BR N ,
|
|
the number of pages, and the id string passed by the caller.
|
|
This script sends by
|
|
.IR mail (1)
|
|
notification to a list of recipients kept in the file
|
|
.BR /mail/faxqueue/faxrecipients ;
|
|
the script and the list
|
|
should be edited to match local needs.
|
|
.I Faxreceive's
|
|
options are:
|
|
.TP
|
|
.B -s
|
|
specify a different spool directory; the default is
|
|
.BR /mail/faxqueue .
|
|
.TP
|
|
.B -v
|
|
verbose: write to the log file all communications with
|
|
the modem.
|
|
.PP
|
|
.I Faxsend
|
|
transmits a FAX to
|
|
.IR address .
|
|
.I Page1
|
|
and all arguments that follow
|
|
are names of files containing G3 encoded
|
|
FAX images, one per page.
|
|
.PP
|
|
.I Fax
|
|
is a shell script that converts to G3 format
|
|
PostScript, G3, text, or other files acceptable to
|
|
.IR lp (1)
|
|
and queues the result
|
|
to be transmitted to a FAX machine.
|
|
A standard cover sheet, derived from
|
|
.BR /sys/lib/fax/h.ps ,
|
|
is sent before the message.
|
|
.I Telno
|
|
is the destination telephone number.
|
|
.I Recipient
|
|
is the name of the recipient to be placed
|
|
on the cover sheet.
|
|
If no
|
|
.I files
|
|
are specified, standard input is converted and sent.
|
|
The
|
|
.B -v
|
|
option invokes
|
|
.IR page (1)
|
|
on the generated G3 files
|
|
instead of transmitting them via FAX machine.
|
|
.SH EXAMPLE
|
|
Start the dialer on a PC, then use
|
|
.I con
|
|
to phone out.
|
|
.IP
|
|

|
telco /dev/eia1

.PP
|
|
The connection will be made at the highest
|
|
negotiable baud rate. To use the
|
|
best negotiable compression scheme as well:

.SH BUGS
|
|
.PP
|
|
These programs require the Class 2 facsimile interface. This means that
|
|
.I faxsend
|
|
and
|
|
.I faxreceive
|
|
will not work on most portable computers since they have Class 1
|
|
interfaces.
|
|
.PP
|
|
The modem specific information is currently built into the source.
|
|
This should be in a user modifiable file.
