35.Sh NAME
36.Nm remote
37.Nd remote host description file
38.Sh DESCRIPTION
39The systems known by
40.Xr tip 1
41and their attributes are stored in an
42.Tn ASCII
43file which
44is structured as described by
45.Xr capfile 5 .
46Each line in the file provides a description for a single
47.Em system .
48Fields are separated by a colon
49.Pq Dq \&: .
50Lines ending in a \e character with an immediately following newline are
51continued on the next line.
52.Pp
53The first entry is the name(s) of the host system.
54If there is more than one name for a system, the names are separated
55by vertical bars.
56After the name of the system comes the fields of the description.
57A field name followed by an `=' sign indicates a string value follows.
58A field name followed by a `#' sign indicates a following numeric value.
59.Pp
60Entries named
61.Dq tip*
62and
63.Dq cu*
64are used as default entries by
65.Xr tip 1 ,
66and the
67.Xr cu 1
68interface to
69.Xr tip 1 ,
70as follows.
71When
72.Xr tip 1
73is invoked with only a phone number, it looks for an entry
74of the form
75.Dq tip300 ,
76where 300 is the baud rate with
77which the connection is to be made.
78When the
79.Xr cu 1
80interface is used, entries of the form
81.Dq cu300
82are used.
83.Sh CAPABILITIES
84Capabilities are either strings (str), numbers (num), or boolean flags (bool).
85A string capability is specified by
86.Em "capability=value" ;
87for example,
88.Dq Li dv=/dev/harris .
89A numeric capability is specified by
90.Em "capability#value" ;
91for example,
92.Dq Li xa#99 .
93A boolean capability is specified by simply listing the capability.
94.Bl -tag -width indent
95.It Cm \&at
96(str)
97Auto call unit type.
98.It Cm \&br
99(num)
100The baud rate used in establishing
101a connection to the remote host.
102This is a decimal number.
103The default baud rate is 300 baud.
104.It Cm \&cm
105(str)
106An initial connection message to be sent to the remote host.
107For example, if a host is reached through a port selector, this might
108be set to the appropriate sequence required to switch to the host.
109.It Cm \&cu
110(str)
111Call unit if making a phone call.
112Default is the same as the `dv' field.
113.It Cm \&dc
114(bool)
115This host is directly connected, and tip should not expect carrier detect
116to be high, nor should it exit if carrier detect drops.
117.It Cm \&di
118(str)
119Disconnect message sent to the host when a
120disconnect is requested by the user.
121.It Cm \&du
122(bool)
123This host is on a dial-up line.
124.It Cm \&dv
125(str)
126.Ux
127device(s) to open to establish a connection.
128If this file refers to a terminal line,
129.Xr tip 1
130attempts to perform an exclusive open on the device to ensure only
131one user at a time has access to the port.
132.It Cm \&el
133(str)
134Characters marking an end-of-line.
135The default is
136.Dv NULL .
137`~' escapes are only
138recognized by
139.Xr tip 1
140after one of the characters in `el',
141or after a carriage-return.
142.It Cm \&fs
143(str)
144Frame size for transfers.
145The default frame size is equal to
146.Dv BUFSIZ .
147.It Cm \&hd
148(bool)
149The host uses half-duplex communication, local
150echo should be performed.
151.It Cm \&hf
152(bool)
153Use hardware (RTS/CTS) flow control.
154.It Cm \&ie
155(str)
156Input end-of-file marks.
157The default is
158.Dv NULL .
159.It Cm \&oe
160(str)
161Output end-of-file string.
162The default is
163.Dv NULL .
164When
165.Xr tip 1
166is transferring a file, this
167string is sent at end-of-file.
168.It Cm \&pa
169(str)
170The type of parity to use when sending data
171to the host.
172This may be one of
173.Sy even ,
174.Sy odd ,
175.Sy none ,
176.Sy zero
177(always set bit 8 to zero),
178.Sy one
179(always set bit 8 to one).
180The default is even parity.
181.It Cm \&pn
182(str)
183Telephone number(s) for this host.
184If the telephone number field contains an @ sign,
185.Xr tip 1
186searches the file
187.Pa /etc/phones
188file for a list of telephone numbers;
189see
190.Xr phones 5 .
191.It Cm \&tc
192(str)
193Indicates that the list of capabilities is continued in the named
194description.
195This is used primarily to share common capability information.
