	Written by Oliver von Bueren, ovb@swissmail.com, 12-Nov-1996 
	The following is only an addition to the ESTIC program, which is Copyright
	by Ullrich von Bassewitz. It's free to integrate into ESTIC as long as
	the terms for the original program from UvB are met.  
	There is absolutely no guarantee that it will work on any other system,
	it just works for me on my system.

I Julian Stacey <jhs@freebsd.org> have tried compiling without the 
	Port->DTROff ();
patch & can confirm for Ullrich, it is necessary, without it, I get
a communications timeout. Thanks Oliver.
