Bug 53551

Description of Problem:
When using the updated telnet client to connect to a Bianca/BrickXL (a ISDN dialin router), the default linemode has changed from the behaviour of telnet-0.16-6 (RH 6.2 default).
When using 0.16-6, linemode is negotiated as follows:

telnet> status
Connected to xxxxxxxxxxxxx
Operating with LINEMODE option
.....

Using 0.17.6x-18:
telnet> status
Connected to xxxxxxxxxxx
Operating in obsolete linemode
....


Unfortunately, the router in question does not like the obsolete linemode (this is how I noticed the problem).


Version-Release number of selected component (if applicable):
0.17.6x-18


How Reproducible:
Always

Steps to Reproduce:
1. Use telnet to connect to the router in question
2. Issue a telnet escape sequence
3. use "status" to check linemode

Actual Results:
telnet is using "obsolete linemode"


Expected Results:
telnet should use "LINEMODE"


Additional Information:
Looking at a tcpdump output of the connection I noticed that telnet-0.16-6 (the old one) sends one packet more than telnet-0.17 (the new one).
The packet in question is sent from the client to the server, and contains option negotiations.
The options negotiated in 0.16 but not in 0.17 are:
- Do suppress go ahead
- will Terminal Type
- will negotiate about window size
- will Terminal Speed
- will Remote Flow Control
- will Linemode                             (sic!)
- will New Environment Option
- Do Status
