Thanks. I'm trying to use chirp through my Yaesu SCU-17 interface box which has serial ports and a sound card.  All my apps use that interface for CAT control so I assumed it should work with chirp.  It uses a Silicon Labs Dual CP2105 USB to UART bridge and a Silicon Labs driver version 6.7.4.261.  And the settings on that port in the device manager match the radio: 4800,8,N,1. Although I'm not so sure on the flow control.  In fldigi, for example, I need to enable RTS/CTS flow control for CAT to work.  But, in the device manager, the only options for flow control are None, Hardware, or Xon/Xoff.

If you are using Windows, use device manager to see what come port you are using. Check properties, and I think advanced. That will show you the speed that com port is set at. Also check to see if your cable is a Prolific. If it is, roll your driver back to 3.2.0.0. See www.miklor.com for more info.

I'm not getting chirp to communicate with my Yaesu FT-450D and I'm suspecting it's a baud rate issue.  My 450D is at the factory default of 4800 baud, and I don't know what chirp uses by default or how to change it's default.  I have no problem changing the radio to match what chirp is expecting, but I'd rather not do it by trial-and-error....  So, can anyone tell me what baud rate chirp is using?  Thanks!
