(e.g., mh1212,boston5551212 ). For the hard-wired devices, this
field contains the same string as used for the device field.
login The login information is given as a series of fields and
subfields in the format
[expect send]
where expect is the string expected to be read and send is the
string to be sent when the expect string is received.
The expect field may be made up of subfields of the form
expect [-send-expect]...
where the send is sent if the prior expect is not successfully
read and the expect following the send is the next expected
string. (For example, login--login will expect login; if it gets it,
the program will go on to the next field; if it does not get login ,
it will send nothing followed by a new line, then expect login
again.) If no characters are initially expected from the remote
machine, the string “” (a null string) should be used in the first
expect field.
There are two special names available to be sent during the
login sequence. The string EOT will send an EOT character,
and the string BREAK will try to send a BREAK character.
(The BREAK character is simulated using line speed changes
and null characters and may not work on all devices and/or
systems.) A number from 1 to 9 may follow the BREAK (e.g.,
BREAK1 , will send 1 null character instead of the default of 3).
Note that BREAK1 usually works best for 300/1200-baud
lines.
There are several character strings that cause specific actions when they are a
part of a string sent during the login sequence.
\s Send a space character.
\d Delay one second before sending or reading more characters.
\c If at the end of a string, suppress the new-line that is normally
sent. Ignored otherwise.
\N Send a null character.
These character strings are useful for making uucp communicate via direct lines
to data switches.
A typical entry in the
L.sys file would be
sauron Any xns xns xns "" ^M\c ogin:--ogin: uucp assword: censored
The expect algorithm matches all or part of the input string as illustrated in the
password field above.
