Looks as if your looking for it to act like the Hytera CPS... short answer no. All USB's are labeled as com port. (that I have dealt with in KWD)
I have heard from a couple of people the USB is faster than the serial cable (which I have).
but for the most part, it's still a LOT OF RADIO in that code plug. 345 (V) and 413 (U) channels takes about 3 to 3 and a half minutes.
By the way gang, I have on good word from Georgia, the multi-deck option and next firmware update due out
the September time frame. I also have the KCH-20R on the 5700, looks awesome. I will have pictures up on nxdninfo.com in a few days when I get it installed in my work truck, then the 5800 will get mounted
in the back (dash mount currently) and married to the 5700 when the cable comes out. One control head, two rf decks, P25, FPP and NXDN Trunking. OH YEAH. Guess I will be getting my TK-5720 cleaned up and think about selling it (has the DES/AES-OFB module in it).
cheers!
