[ICOM] Splitting the CI-V data stream

[Gary P. Fiber]

Ya I had forgot you ops are getting all that information via the CI-V 
these days.
I go clear back the IC-735 4 bit data days. Well sounds like Data 
Collisions are more prevalent with more devices connected on the CI-V 
data buss.
Polling was the way to go when the Transceive function got in the way 
having 2 or more rigs connected to the CI-V buss but now it seems you 
need both.
No more ideas from me to solve it.
