Horizon EX sends NAV frequencies to SL30, but won't send COM freqs.

Plane has 3 EX's (with #2 communicating to SL30) and a 430W.
I would really like EX#2 to send COM freqs like my old Horizon WS in the same slot did.

Settings:
430W as “430W-1”.
SL30 as “SL30-2”.
“COM1 Device” = 430W-1.
“COM2 Device” = SL30-2.
"Send SL30-2 Data" - all Yes.
"Send SL30-2 Commands" - only EX#2 is No.
(Have tried a lot of other combos on all these settings.)

Software:
SL30: NAV 1.40, COM 2.2, DSP = 1.20.
GRT: 3.02

"COM1 Device" can't be set to 430W-1 because the EFIS can't control the frequencies of a 430W. This should be set to "None" so the EFIS knows it can't control COM1.

With the serial port input and output set to 9600 SL30-2 and the COM2 Device set to SL30-2, sending frequencies should always work from EX#2.
