I had reported a similar problem 10 days ago with tcsh and telnet.
If you try Ctrl-S while e.g. a long ls -l listing, the output stops
as expected, but unfortunately you'll never get it to wake up.
This is absolut reproducable!
Neither Ctrl-Q nor Ctrl-C helps. The shell doesn't react to any
key. You have to close the connection. I have tried, to reproduce it
under different circumstances.
The telnetd is out of Sergeys remote package.
Shells are bash, tcsh and pdksh.
Telnet is either NT telnet or Teraterm Version 2.2,
I've tested it with winsup-981223 and winsup-981230:

telnet, system startet with CYGWIN=notty	shell hangs
telnet, system startet with CYGWIN=tty		shell hangs
console, notty					no hangs
console, tty					no hangs

This let me guess, it's a problem with telnetd from Sergeys package.
