If the remote host does not supporting Kerberos the standard Berkeley
authorization mechanism is used.
The options are as follows:

parity bits are stripped except when the remote side's stop and start

``~'' by default.
This specification may be as a literal character, or as an octal
value in the form \nnn.

A line of the form ``<escape char>.'' disconnects from the remote host.
Similarly, the line ``<escape char>^Z'' will suspend the
session, and ``<escape char><delayed-suspend char>'' suspends the
send portion of the rlogin, but allows output from the remote system.
By default, the tilde (``~'') character is the escape character, and
normally control-Y (``^Y'') is the delayed-suspend character.
All echoing takes place at the remote site, so that (except for delays)
