NAME
remote - remote host description file

DESCRIPTION
The systems known by tip(1) and their attributes are stored in an ASCII
file which is structured somewhat like the termcap(5) file. Each line in
the file provides a description for a single system. Fields are separat-
ed by a colon (‘‘:’’). Lines ending in a character with an immediately
following newline are continued on the next line.

The first entry is the name(s) of the host system. If there is more than
one name for a system, the names are separated by vertical bars. After
the name of the system comes the fields of the description. A field name
followed by an ‘=’ sign indicates a string value follows. A field name
followed by a ‘#’ sign indicates a following numeric value.

Entries named ‘‘tip*’’ and ‘‘cu*’’ are used as default entries by tip,
and the cu interface to tip, as follows. When tip is invoked with only
a phone number, it looks for an entry of the form ‘‘tip300’’, where 300
is the baud rate with which the connection is to be made. When the cu
interface is used, entries of the form ‘‘cu300’’ are used.

CAPABILITIES
Capabilities are either strings (str), numbers (num), or boolean flags
(bool). A string capability is specified by capability=value; for exam-
ple, ‘‘dv=/dev/harris’’. A numeric capability is specified by
capability#value; for example, ‘‘xa#99’’. A boolean capability is speci-
fied by simply listing the capability.

at (str) Auto call unit type.

br (num) The baud rate used in establishing a connection to the re-
mote host. This is a decimal number. The default baud rate is
300 baud.

cm (str) An initial connection message to be sent to the remote
host. For example, if a host is reached through port selector,
this might be set to the appropriate sequence required to switch
to the host.

cu (str) Call unit if making a phone call. Default is the same as
the ‘dv’ field.

di (str) Disconnect message sent to the host when a disconnect is
requested by the user.

du (bool) This host is on a dial-up line.

dv (str) UNIX device(s) to open to establish a connection. If this
file refers to a terminal line, tip(1) attempts to perform an ex-
clusive open on the device to insure only one user at a time has
access to the port.

el (str) Characters marking an end-of-line. The default is NULL.
‘~’ escapes are only recognized by tip after one of the charac-
ters in ‘el’, or after a carriage-return.

fs (str) Frame size for transfers. The default frame size is equal
to BUFSIZ.

hd (bool) The host uses half-duplex communication, local echo should

be performed.

ie (str) Input end-of-file marks. The default is NULL.

oe (str) Output end-of-file string. The default is NULL. When tip
is transferring a file, this string is sent at end-of-file.

pa (str) The type of parity to use when sending data to the host.
This may be one of ‘‘even’’, ‘‘odd’’, ‘‘none’’, ‘‘zero’’ (always
set bit 8 to zero), ‘‘one’’ (always set bit 8 to 1). Tradition-
ally tip’s default parity is even parity. However, MachTen ex-
pects 8 bits for tty input, so under MachTen, tip’s default pari-
ty is none.

pn (str) Telephone number(s) for this host. If the telephone number
field contains an @ sign, tip searches the file /etc/phones file
for a list of telephone numbers; (See phones(5).)

tc (str) Indicates that the list of capabilities is continued in the
named description. This is used primarily to share common capa-
bility information.

Here is a short example showing the use of the capability continuation
feature:

UNIX-1200: :dv=/dev/cau0:el=^D^U^C^S^Q^O@:du:at=ventel:ie=#$%:oe=^D:br#1200:
arpavax|ax: :pn=7654321%:tc=UNIX-1200
