remote - remote host description file
The systems known by and their attributes are stored in an ASCII file that is structured somewhat like the file. Each line in the file
provides a description for a single system. Fields are separated by colons (:). Lines ending in a backslash () followed immediately by a
newline character are continued on the next line.
The first entry is the names 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 equal sign (=) indicates a string value fol-
lows. A field name followed by a number sign (#) indicates a following numeric value.
Entries named ``tip*'' and ``cu*'' are used as default entries by and the interface to as follows. When is invoked with only a phone num-
ber, 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 interface
is used, entries of the form ``cu300'' are used.
Capabilities are either strings (str), numbers (num), or Boolean flags (bool). A string capability is specified by capability=value; for
example, A numeric capability is specified by capability#value; for example, A Boolean capability is specified by simply listing the capa-
at (str) Autocall unit type. This string is what is searched for in to decide if the generic dialer is to be used. For further informa-
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
cm (str) An initial connection message to be sent to the remote host. For example, if a host is reached through 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 field.
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 devices to open to establish a connection. If this file refers to a terminal line, 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. Tilde (~) escapes are recognized by only after one of the characters
in 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.
ie (str) Input end-of-file marks. The default is NULL.
md (bool) A hardwired device being used accepts modem control signals. Used when is not present but modem signals are to be used.
oe (str) Output end-of-file string. The default is NULL. When tip 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. The type can be one of even, odd, none, zero (always set bit 8 to
zero), or 1 (always set bit 8 to 1). The default is even parity.
pn (str) Telephone numbers for this host. If the telephone number field contains an @ sign, searches the file file for a list of tele-
phone numbers. For further information, see
tc (str) Indicates that the list of capabilities is continued in the named description. This is used primarily to share common capabil-
Here is a short example showing the use of the capability continuation feature:
