Re: [Elecraft] How to test serial communications?
Thanks, Kevin. I assume (though the referenced test procedure doesn't say it), that with pins 2 and 3 shorted to each other, each character you type on hyperterminal should be echoed on-screen twice, once locally and once by the loopback. If that's the case. then it may be that I just have a bad *computer* port, which would be good news indeed. 73, Pete N4ZR The World Contest Station Database, updated daily at www.conteststations.com The Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com On 6/6/2010 4:51 PM, R.

Re: [Elecraft] How to test serial communications?
Pete, If you are using HyperTerminal (or most other terminal emulation programs), you can turn local echo on or off. When doing the kind of testing you're doing, I turn it OFF to avoid confusion. (1) In the New Connection - HyperTerminal screen, select File Properties. (2) In the New Connection Properties dialog box, click the Settings tab, then click the ASCII Setup... button. (3) In the ASCII Setup dialog box, make sure the Echo typed characters locally checkbox is UNCHECKED. (4) Click OK to commit the ASCII Setup settings. (4) Select the COM port you are going to test in the New Connection Properties dialog box and click OK to commit all settings for that port. Then the only thing that will appear on your screen as you type are the looped-back characters.

Re: [Elecraft] How to test serial communications?
Sadly, doing this test with a brand new USB-to-serial cable, it works fine. However, that cable to the K3 yields nothing, and there are some funky voltages on U1 on the KIO3. I'm afraid I may have blown the RS-232 transceivers on both the computer and K3 ends. Time for a changeout. 73, Pete N4ZR The World Contest Station Database, updated daily at www.conteststations.com The Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com On 6/7/2010 9:34 AM, Bill VanAlstyne W5WVO wrote: Pete, If you are using HyperTerminal (or most other terminal emulation programs), you can turn local echo on or off.

Just jump pins 2 and 3 of the connector (or cable) coming from the computer and activate any terminal program. Set it for no handshaking. If the port is working, you should see an echo of anything you type. -- Vic, K2VCO Fresno CA http://www.qsl.net/k2vco/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Pete, One of the things that lightning create errors in or modify digital memory. One thing I would try is going into the K3 menu and re-setting anything associated with digital comm, like bit rate, etc. Then do the same thing in your computer. If that solves the problem, there may be other errors lucking about. :) 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] How to test serial communications?
I assume you're restarted both the computer and the K3. You need to eliminate either the computer or the K3 as the problem. Test the computer serial port by following these instructions. http://www.reliableracing.com/downloads/LoopBackTest.pdf If the port talks to itself the problem is with the K3.
