Thanks again to all who replied to my message. The thing leaves me with
some doubts is that I still using an old version of LPT interface from CT
manual and it continues running well also with the mods to the software
made by Ken. It's better so! Hope to have paddle support in a near future.
See you all starting tomorrow (Wednesday) from 1A0KM (CW and RTTY).
ciao Sante
