Telco is a file server that provides a network interface to Hayes
telephone dialers. The interface is the same as that provided
by ip(3) and can be used by any program that makes network connections
using dial(2). The network addresses used by telco are telephone
The options are
Some control of outgoing calls can be encoded in the address.
Normally, addresses are of the form telco!number, where 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 !'s. The dialing options are
Telco also answers incoming calls. Upon receiving a facsimile
call, telco starts the script /rc/bin/service/telcofax. For data
calls it starts /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., /net/telco/0/data, and the type
of modem. Currently, the only modem types supported are:
All other modems are assumed to be compatible with the standard Hayes command subset.
Faxreceive is normally started by /rc/bin/service/telcofax. It
reads and spools a CCITT Group 3 (G3) encoded FAX, and then starts
the script /sys/lib/fax/receiverc, passing it four arguments:
the spool file name, Y (for success) or N, the number of pages,
and the id string passed by the caller. This
script sends by mail(1) notification to a list of recipients kept
in the file /mail/faxqueue/faxrecipients; the script and the list
should be edited to match local needs. Faxreceive's options are:
Faxsend transmits a FAX to address. Page1 and all arguments that follow are names of files containing G3 encoded FAX images, one per page.
Fax is a shell script that converts to G3 format PostScript, G3,
text, or other files acceptable to lp(1) and queues the result
to be transmitted to a FAX machine. A standard cover sheet, derived
from /sys/lib/fax/h.ps, is sent before the message. Telno is the
destination telephone number. Recipient is the name
of the recipient to be placed on the cover sheet. If no files
are specified, standard input is converted and sent. The –v option
invokes page(1) on the generated G3 files instead of transmitting
them via FAX machine.
Start the dialer on a PC, then use con to phone out.
These programs require the Class 2 facsimile interface. This means
that faxsend and faxreceive will not work on most portable computers
since they have Class 1 interfaces.
The modem specific information is currently built into the source.
This should be in a user modifiable file.
