SetupComm is used to set the size of the serial port receive and transmit buffers. The K3 Utility is setting them to constant values, 4096 bytes each.
This command is interpreted by the serial port's device driver. Would you check that you have up-to-date device drivers for the device you're using? If it's the Elecraft KUSB, there is a link to the chip vendor's web site in K3 Utility Help, Troubleshooting, USB to Serial Adapter Troubleshooting. The most recent set of drivers for the Elecraft KUSB are the PL-2303 drivers dated 12/2/2009. They're the 2nd item on this web page: http://www.prolific.com.tw/eng/downloads.asp?ID=31 I'm using this driver installer for my XP system and my Windows 7 64-bit system and I test every K3 Utility version with them. 73 de Dick, K6KR -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Fred Jensen Sent: Sunday, April 04, 2010 2:43 PM To: Elecraft Reflector Subject: [Elecraft] K3 Utility problem I decided to check for new firmware and the K3 Utility gives me an error when I select the COM port [COM4] connected to the radio: SetupComm failed on 'COM4' Error=87: The parameter is incorrect This worked fine the last time I used it maybe two months ago. I know the CAT line to the computer is working OK because N1MM gets the radio frequency and knows the radio is there. Any help? 73, Fred K6DGW Auburn CA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
