dlportio is only required for LPT port keying. I would not recommend trying that under Wine. You could use serial port keying (one transistor circuit) or winkey - a dedicated keyer that runs off a serial port. Jet is the jet engine that supports the database used by the program. If you have been successful in getting the program to run under Wine, please post the steps so I can refer people to it who ask. I don't run linux, I just don't have time to. Please also indicate what windows and functions you have been able and *not able* to make work under Wine. Of particular interest are: Windows: Log & Entry Bandmap Packet Info Rotor support Functions: Radio interfacing LPT port keying (certainly not) Serial port keying Winkey keying Multi user using LAN Telnet (packet window) Launching of other programs for help, QRZ lookup, reporting application etc. The above windows and functions were chosen represent distinct areas that might be problematic with Wine. 73, Tom - N1MM
