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

201The

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