34.Sh NAME
35.Nm remote
36.Nd remote host description file
37.Sh DESCRIPTION
38The systems known by
39.Xr tip 1
40and their attributes are stored in an
41.Tn ASCII
42file which
43is structured somewhat like the
44.Xr termcap 5
45file.
46Each line in the file provides a description for a single
47.Em system .
48Fields are separated by a colon (``:'').
49Lines ending in a \e character with an immediately following newline are
50continued on the next line.
51.Pp
52The first entry is the name(s) of the host system.
53If there is more
54than one name for a system, the names are separated by vertical bars.
55After the name of the system comes the fields of the description.
56A field name followed by an `=' sign indicates a string value.
57A field name followed by a `#' sign indicates a numeric value.
58.Pp
59Entries named ``tip*'' and ``cu*'' are used as default entries by
60.Xr tip 1 ,
61and the
62.Xr cu 1
63interface to
64.Nm tip ,
65as follows.
66When
67.Nm tip
68is invoked with only a phone number, it looks for an entry
69of the form ``tip300'', where 300 is the data rate with
70which the connection is to be made.
71When the
72.Nm cu
73interface is used, entries of the form ``cu300'' are used.
74.Sh CAPABILITIES
75Capabilities are either strings (str), numbers (num), or boolean
76flags (bool).
77A string capability is specified by
78.Em capability Ns Ar = Ns Em value ;
79for example, ``dv=/dev/harris''.
80A numeric capability is specified by
81.Em capability Ns Ar # Ns Em value ;
82for example, ``xa#99''.
83A boolean capability is specified by simply listing the capability.
84.Bl -tag -width indent
85.It Cm \&at
86(str)
87Auto call unit type.
88.It Cm \&br
89(num)
90The data rate (bits per second) used for communications on the
91serial port.
92When a modem is used, the data rate used to communicate
93with the remote modem may be different than this rate.
94This is a decimal number.
95The default rate is 9600 bits per second.
96.It Cm \&cm
97(str)
98An initial connection message to be sent to the remote host.
99For example, if a host is reached through a port selector, this
100might be set to the appropriate sequence required to switch to the host.
101.It Cm \&cu
102(str)
103Call unit if making a phone call.
104Default is the same as the `dv' field.
105.It Cm \&di
106(str)
107Disconnect message sent to the host when a disconnect is requested by
108the user.
109.It Cm \&du
110(bool)
111This host is on a dial-up line.
112.It Cm \&dv
113(str)
114.Ux
115device(s) to open to establish a connection.
116If this file refers to a terminal line,
117.Xr tip 1
118attempts to perform an exclusive open on the device to ensure only
119one user at a time has access to the port.
120.It Cm \&el
121(str)
122Characters marking an end-of-line.
123The default is
124.Dv NULL .
125`~' escapes are only
126recognized by
127.Nm tip
128after one of the characters in `el', or after a carriage-return.
129.It Cm \&fs
130(str)
131Frame size for transfers.
132The default frame size is equal to
133.Dv BUFSIZ .
134.It Cm \&hd
135(bool)
136The host uses half-duplex communication, local echo should be performed.
137.It Cm \&ie
138(str)
139Input end-of-file marks.
140The default is
141.Dv NULL .
142.It Cm \&oe
143(str)
144Output end-of-file string.
145The default is
146.Dv NULL .
147When
148.Nm tip
149is transferring a file, this
150string is sent at end-of-file.
151.It Cm \&pa
152(str)
153The type of parity to use when sending data
154to the host.
155This may be one of ``even'',
156``odd'', ``none'', ``zero'' (always set bit 8 to zero),
157``one'' (always set bit 8 to 1).
158The default is even parity.
159.It Cm \&pn
160(str)
161Telephone number(s) for this host.
162If the telephone number field contains an @ sign,
163.Nm tip
164searches the file
165.Pa /etc/phones
166file for a list of telephone numbers (see
167.Xr phones 5 ) .
168.It Cm \&tc
169(str)
170Indicates that the list of capabilities is continued in the named
171description.
172This is used primarily to share common capability information.
173.El
174.Sh FILES
175.Bl -tag -width /etc/remote -compact
176.It Pa /etc/remote
177The
178.Nm
179host description file resides in
180.Pa /etc .
181.El
182.Sh EXAMPLES
183Here is a short example showing the use of the capability continuation
184feature.
185It defines a 56k modem connection on the first serial port at 115200
186bits per second, no parity using the Hayes command set with standard
187line editing and end of file characters.
188The arpavax entry includes everything in the UNIX-57600 entry plus
189the phone number for arpavax (in this case an @ character so that it
190is retrieved from the environment).

201.Sh HISTORY
202The
203.Nm
204file format appeared in
205.Bx 4.2 .
206.Sh BUGS
207The
208.Xr tip 1
209utility uses its own notion of the serial ports data rate rather than the
210system default for a serial port.
