Re: Telnet connect to Cygwin gives no response


Hi Jeremy,

Thank you for your reply.

I totally agree on the fact that the source of our problems is ProComm
Plus. We are able to use whatever we want/can. We are using Putty too
now, but Putty doesn't have scripting support. The scripting support
in ProComm is great and all our scripts are in "aspect". So we prefer
to use ProComm.

I'm looking into something else for ProComm, but it's not that easy to
adapt to a new scripting language and until that time I would like to
use cygwin as a "pass-trough" server.
