Re: [Elecraft] Test serial-to-USB converter

Jan, In the "good old days", you could check a serial port by connecting pin 2 to pin3 at the end of the serial cable. Set the port to software handshaking (or else connect the control pins together in a similar manner-I don't recall the pin numbers). Then run a dumb terminal program. What

A multitude of USB 'sins' can often be cured by a complete powering down of the computer, including pulling the power cord (on desktops) and removing the battery (laptops). A soft reboot doesn't always reset the hardware but 10+ seconds of zero power to them usually does. In this condition,
