I have CW, PTT, and FSK working perfectly with each utilizing a different line on the same comport. Each line uses a 2N2222/10K resistor.
Works in Dxbase, Works in Writelog, Works for MMTTY, Works for PSK programs. Total cost did not exceed $5.00 plus cables/connectors. It was so cheap and easy that the Rigblaster MUST be a wiser choice. <wink> ----------------------------------------------------- Hey!
