I am trying to help a friend set-up FLDIGI on his new laptop using his Microham Digikeyer. Using the device router for the digikeyer (control port 5 and PTT port 6) the digikeyer PTT test button does toggle the PTT. However when using FL-Digi , frequency display corresponds with the Icom 746 but the T/R button fails to place the Icom in to transmit mode. Any ideas ? When configuring FL-DIGI, we did try to use HAMLIB and PTT via CAT control, but that did not produce a PTT wither.
