remote host description

DESCRIPTION
The systems known by
tip(1) and their
attributes are stored in an ASCII file which is structured as decribed by
capfile(5). Each line in the
file provides a description for a single
system. Fields are
separated 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(1), and the
cu(1) interface to
tip(1), as follows. When
tip(1) 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(1) 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
example, “
dv=/dev/harris
”. A numeric
capability is specified by
capability#value; for example,
“
xa#99
”. A boolean capability is specified
by simply listing the capability.
-
-
- at
- (str) Auto call unit type.
-
-
- br
- (num) The baud rate used in establishing a connection to
the remote 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 a 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.
-
-
- dc
- (bool) This host is directly connected, and tip should not
expect carrier detect to be high, nor should it exit if carrier detect
drops.
-
-
- 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
exclusive open on the device to ensure 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(1) after one of the
characters 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.
-
-
- hf
- (bool) Use hardware (RTS/CTS) flow control.
-
-
- ie
- (str) Input end-of-file marks. The default is
NULL
.
-
-
- oe
- (str) Output end-of-file string. The default is
NULL
. When
tip(1) 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 one). The default is even
parity.
-
-
- pn
- (str) Telephone number(s) for this host. If the telephone
number field contains an @ sign,
tip(1) 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
capability 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
