The RFCs are - 1692, 1646, 1073, 927, 933, 1041, 1408, 1468, 
               1079, 1080, 885.

1079       C. Hedrick, "Telnet terminal speed option", 12/01/1988. (Pages=3) 
	   (Format=.txt) 

1080       C. Hedrick, "Telnet remote flow control option", 11/01/1988.  
	   (Pages=4) (Format=.txt) (Obsoleted by RFC1372) 

0885        J. Postel, "Telnet end of record option", 12/01/1983. (Pages=2) 
	   (Format=.txt) 

These three are supported by cisco communication servers.  1079 is/was used
for speed matching between autobaud and "milking machine" lines.  1080 for
allowing servers to turn off SW flow control for file uploads, and 885 is
used under rather obscure circumstance to indicate the packet delimitation
of an x.25 data stream when it is "translated" to a telnet session.

In addition, I beleive 885 is rather extensively used within the TN3270
"extension" of telnet.


0927        B. Anderson, "TACACS user identification Telnet option", 
	   12/01/1984. (Pages=4) (Format=.txt) 

Note that this predates the use of "TACACS" on cisco or other terminal
servers.  These were real milnet TACs they are talking about, and I doubt
that the option has much practical application nowdays.


1041       Y. Rekhter, "Telnet 3270 regime option", 01/01/1988. (Pages=6) 
	   (Format=.txt) 

This was a well-meant attempt to improve the transition to tn3270 mode,
but I don't think and of the host implementations ever supported it, and
it is now deprecated.  There is a tn3270 group within the IETF codifying
current practices and possible extensions for tn3270.
