I have tried to install the latest RMS express on a Dell Desktop also running SmartSDR, I followed the steps provided by Tim of FlexRadio. Under device manager I see COM105 and Com5 as the Virtual Serial ports. I assigned Com105 to the Radio Control Port/ serial port and PTT Port/Serial Port to Com 5. In the SmartCat the Serial Com 5 is RMS Express and there is no Com 105. When I open the session in Winlink/Winmor and hit start it tries to connect and SendID and the Winmor Sound card displays the receive levels but no transmit. After calling out a station it fails to connect. Can someone please tell me what is wrong, when I hit the test transmit tone, there is no transmit tone like I saw in the video. The SmartSDR 2.9 version also takes a while to bootup on my Dell PC and show the connect bar to my Flex6600 radio. The PC is directly connected via Ethernet to the radio and sometimes I have to reboot the computer, it seems to show the Radio connect option intermittently.
