Allow an eight-bit input data path at all times; otherwise parity bits are stripped except when the remote side’s stop and start characters are other than ^S/^Q.
-D
Set the TCP_NODELAY socket option which can improve interactive response at the expense of increased network load.
-E
Stop any character from being recognized as an escape character. When used with the -8 option, this provides a completely transparent connection.
-d
Turn on socket debugging (see setsockopt(2)) on the TCP sockets used for communication with the remote host.
-e
Allow user specification of the escape character, which is "~" by default. This specification may be as a literal character, or as an octal value in the form \nnn.
-i
Allow the caller to specify a different local name to be used for authentication. This option is restricted to processes with uid 0.
-l
Specify a different username for the remote login. If this option is not specified, your local username will be used.
A line of the form "<escapechar.>" disconnects from the remote host. Similarly, the line "<escapechar^Z>" will suspend the rlogin session, and "<escape char<delayed-suspend char>>" suspends the send portion of the rlogin session, 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) the rlogin is transparent. Flow control via ^S/^Q and flushing of input and output on interrupts are handled properly.
