[TenTec] OMNI VI serial PTT

[Philip Leonard WVØT]

I have an Omni VI opt3 and I am trying to use it with MixW but I can't 
get MixW to key the radio.  I can change the frequency via MixW but no 
luck getting PTT to work.  I have MixW set for an IC-735.  I have tried 
to use Ham Radio Deluxe but with the same result.  I am using the Omni's 
serial interface.  What am I missing?  Or is there something wrong in 
the Omni?

Also, does anyone have the hex strings to select the various filters in 
the Omni via serial control?

Thanks, Philip
