I downloaded the latest version of GPredict for Windows from Sourceforge a couple of days ago and it works well with the ICOM 910. Here is a log of what GPredict does to read main and sub VFO frequencies: rigctl(d): V '0xb77908e9' 'Main' '' '' TX 7 bytes 0000 fe fe 60 e0 07 d0 fd ..`.... RX 7 characters 0000 fe fe 60 e0 07 d0 fd ..`.... RX 6 characters 0000 fe fe e0 60 fb fd ...`.. fscanf: Success rigctl(d): f '0xb77908e9' '' '' '' TX 6 bytes 0000 fe fe 60 e0 03 fd ..`... RX 6 characters 0000 fe fe 60 e0 03 fd ..`...

RX 7 characters 0000 fe fe 60 e0 07 d0 fd ..`.... RX 6 characters 0000 fe fe e0 60 fb fd ...`.. fscanf: Success GPredict is sending manually all the commands, in particular selecting the VFO, without doing a double swaps (as it is done in the read_split_frequency command in Hamlib) and the reception can continue without interruptions. I do not know if the VFO exchange does the same thing on all the other ICOM radios, but on the 910 this interrupts reception.
