NAME

fone − control ISDN telephone

SYNOPSIS

­fone [options...]

DESCRIPTION

­Fone manages an AT&T 7506 ISDN telephone set.  Program control is supplementary: normal functioning of the phone is not affected.  The set must be equipped with the ProPhone1.5 ROM or equivalent.  To initialize after the ROM is first installed, push the Select, then the ­Data button, and set parameters as follows:

­DATA MODE: B2
­DATA RATE: 19200
­PARITY: SPACE
­LOCAL MODE: AT

­Fone should be run once per terminal session; it accepts commands typed in its window.  If the file ­call.log exists and is writable, it will contain a log of calls.  A permanent log file may be initialized with:

­chmod +a call.log >call.log

Options for ­fone are:

-f file The telephone is controlled through ­file instead of /dev/eia0. 

-l file Calls are logged in ­file instead of call.log. 

­-m The mike is not muted when a call is dialed with the handset down (see below). 

-t cmd The ­t command (see below) runs ­cmd instead of /bin/tel. 

Commands to ­fone are read, one per line, from the standard input. 

c string
Call telephone number string. Non-alphanumeric characters are discarded, and the appropriate prefix (9, 91, or none) is guessed from the length of the result.  (If there is no active call, and ­string begins with a digit, the initial ­c may be omitted.) 

C string
The alphanumeric characters in ­string are dialed exactly as given. 

d Drop the active call, or the last party added to a conference call. 

­h Put the active call on hold. 

k string
Add a party to a conference call. The active call is placed on  hold, and ­string is parsed and dialed.  Once the second call is connected, the ­k command with no argument adds the new call to the previously active call appearance.  If the called party is indisposed, the commands ­d and ­r will drop the second call and reconnect the first. 

q string
Query the local switch for directory entries matching ­string (a surname preceded by up to two initials, like fraser, a fraser, ag fraser, or a g fraser). 

r id Reconnect a call on hold and make it the active call.  If the appearance ­id is omitted, it defaults to that of the lowest numbered call on hold. 

­s Show the id, state, and ­calling ­information for each call. 

t string
Run the tel(1) command on string.

x string
Transfer the active call. The active call is placed in limbo (similar to hold), and ­string is parsed and dialed.  Once the second call is connected, the ­x command with no argument bridges the two calls together and drops the intermediary (you).  If the called party is indisposed, the commands ­d and ­r will drop the second call and reconnect the first. 

. string
Transmits the converted Touch-Tone ­string to the called party; a ­string that begins with a ∗, #, or a digit doesn’t need the preceding ..  (See command ­c above if no call is active.) 

­?  Print a summary of commands. 

The ­c command may be given before or after lifting the handset; if the handset is down, the call is placed with the speaker on so you can hear what’s happening.  The mike is normally muted, but the ­-m flag (see above) overrides this.
