/* ---------- "problem with NCSA telnet and flex i" ---------- */

We found that when flex cut in and blank the screen while
the m/c is connected to other hosts through telnet, the
connections will be lost, ie. the hosts will not reponse,
afterwards. We must then exit telnet and reopen the
connections. Right now we avoid this by turning off flex.
Any expert there can suggest a solution so that we can
still blank the screen and yet have the connections
online?
Please mail your reply besides posting.
Thanks  a thou.

NCSA Telnet must remain in constant contact with the host.  Hosts
typically send a "keepalive" packet every 45 seconds and they give
up on you after 3 to 10 minutes.

So if you have a screen-saver which takes over the CPU and does not
give control back to the application, this problem is unavoidable.
I have been told that Pyro is fixed.  I use Moire 2.1 which does not
have this problem.
