The file lists the types of autodial modems and describes their
The program searches the file when it encounters an field in the file
description. If the string matches a name entry in the file, the and
generic dialing routines are used to place an outgoing call according
to the attributes specified for the modem in the file.
The program uses the same procedure for deciding how to activate an
autodialer modem, except that searches for the brand name field of the
file in the database.
Each line in the file describes how to dial a given type of modem. This
description consists of strings, time delays, and flags that are used
to control the action of any modem. Fields are separated by a colon
(:). Entries that end in a backslash character (\) followed by a new‐
line are continued on the next line.
The first entry is the name or names of the modem. If there is more
than one name for a modem, the names are separated by vertical bars
The fields of the description follow the name. A field name followed
by an equal sign (=) indicates that a string value follows. A field
name followed by a pound sign (#) indicates that a numeric value fol‐
lows. A field name followed by the separating colon (:) represents a
The fields following the name of the modem define the capabilities of
the modem. Capabilities are either strings (str), numbers (num), or
Boolean flags (bool). A string capability is specified as capabil‐
ity=value; for example, ``ss=^A^B''. A numeric capability is specified
by capability#value; for example, ``sd#1''. A Boolean capability is
specified by simply listing the capability. Strings that are not spec‐
ified cause nothing to be issued.
ab (str) Abort string. This string is sent to the modem if is
cd (num) Completion delay. This number gives the time to wait between
completion string characters (in seconds, unless the Boolean
cr (bool) Setting this Boolean causes the program to wait in the
generic dial routine until the modem senses a carrier.
co (str) A modem command string which instructs the modem to change
from the default speed to the speed specified by the xs
cs (str) Completion string. The modem issues this string after
receiving and responding to synchronization and dial strings.
da (num) Dial acknowledge. This number gives the time to wait before
looking for a dial response (in seconds).
db (bool) Debug mode. Setting this Boolean causes the generic dialer
to give more information as it dials.
dd (num) Dial delay. This number gives the time between dial charac‐
ters (in seconds) unless the Boolean is specified.
di (str) Dial initialization. This string is used to start a dialing
sequence (placed just before the number to dial.)
dr (str) Dial response. The modem sends this string if a dialing
sequence that was just issued is successful.
ds (str) Disconnect string. This string is sent to the modem when is
dt (str) Dial termination. This string is used to terminate a dialing
sequence (placed just after the number to dial.)
fd (num) Full delay. This number is the time to wait for a carrier to
be detected (in seconds). If the call is not completed in
this time, an error is returned.
hu (bool) This Boolean causes the modem to hang up the phone if the
line goes away.
is (num) This number specifies the speed the modem must be initialized
at. The conversation speed will later be set as specified by
the xs field.
ls (bool) Use an internal sleep routine rather than for delays. Thus,
all delays are given in microseconds rather than seconds.
os (str) Online string. The modem sends this string after carrier has
rd (bool) Causes a 1-second delay after toggling dtr. This action will
only be taken if the re flag is also set.
re (bool) This Boolean causes the modem to toggle dtr (data terminal
ready) before beginning synchronization. It is used to reset
the present condition of the modem.
rs (str) Replacement string. This string is a single character that
will be substituted for an equal sign (=) or dash (-) in the
number to be dialed. Used so that delay characters can be
represented uniformly, but allowing the correct delay charac‐
ter to be passed to a given modem.
sd (num) Synchronization delay. This number gives the time
between synchronization characters (in seconds unless the
Boolean is specified.)
si (bool) This modem is attached to an interface that cannot return any
characters until carrier is detected. Digital's DMF32 inter‐
face acts in this way.
sr (str) Synchronization response. What the modem sends in response
to a synchronization string.
ss (str) Synchronization string. The first string the modem expects
to receive; a check to see if the modem is operating.
xs (num) Specifies the speed the modem will operate at after initial‐
ization at the default speed per the is field.
