I have a Win98 laptop and a TS850. Using DOS mode I can get CW keying to work on LPT1 but have horrendous problems keeping the COM1 interface to the radio working reliably. Using WINCT under Win98 the COM1 interface to the 850 works reliably but I can't CW keying on LPT1 to work at all. Any hints on WINCT and LPT1? Thanks, John Pescatore K3TN
