This is a Bug discussed in Bug 11621 but not belonging there.
> As the author of NetTerm, SecureNetTerm, SNetTerm and SecureFTP, I am seeing
> the same problem with NetTerm that I see with Putty as it relates to the telnet
> connection problem.
> Our SNetTerm product, as well as the Microsoft telnet.exe DOES NOT have this
> issue.
> Is there been any additional information on this issue that would help us get
> this resolved?  Where to look?  Anytime we can test in the winsock area to help
> resolve the issue?

> I am not sure that this is all that is going on.  Our NetTerm product DOES NOT
> send a SIOCATMARK, yet the behavior is much like Putty's.  That is, it connects
> to the host ok, then about 2-3 seconds after the connect, it freezes.
> Note that it IS NOT a the same place everytime.  That is, if I run NetTerm
> without a script, I cannot type fast enough to enter my userid at the Login:
> prompt before the application locks up.  However if I use a script, it logs in
> and gets to the command line then locks up.
> It appears that some type of timer is involved.
> The really strange thing is our SNetTerm product is not affected by the bug at
> all.  It does a telnet connect and everything works ok.  The same is true for
> the Microsoft telnet.exe program.

> The current version of NetTerm can be downloaded from:
> http://www.securenetterm.com/pub/nt325405.exe
> and includes a 60 day trial period.  If more time is needed, or has been
> downloaded before and trial period has expired, contact me at
> support at securenetterm.com and I will send a new key.

> I found the problem.  It is in the telnet tcpip network code, sort of like the
> Putty problem.  NetTerm locks up when it issues a winsock recv()call for 1 byte
> with MSG_PEEK in the flags field.
