host description file
file describes remote hosts known by
. It is an ASCII file
structured somewhat like the
file. Each line in
the file provides a description for a single remote host. Fields are separated
by a colon (‘:’). Lines ending with a ‘\’
character immediately followed by a 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 (the capabilities).
Capabilities are either strings (str), numbers (num), or boolean flags (bool). A
string capability is specified by
for example, ‘dv=/dev/harris’. A numeric capability is specified
for example, ‘br#19200’. A boolean capability is specified by
simply listing the capability.
- (num) The baud rate used in establishing a connection to
the remote host. This is a decimal number. The default baud rate is 9600
- (bool) This host is directly connected, and
cu(1) should not expect carrier
detect to be high, nor should it exit if carrier detect drops.
- (str) Device to open to establish a connection. If this
file refers to a terminal line,
cu(1) attempts to perform an
exclusive open on the device to ensure only one user at a time has access
to the port.
- Global database.
