I have been trying to use the computer control for my K2/100. I am using the RS232 port on the KPA100. I cannot seem to ever get any response except KY0; to the KY; command. If I send a KY; immediately after KY 123456789012345678901234; while the K2 is still sending the first character, it should respond KY1;, but I get instead KY0;. If I send KY; after the sending is complete I get KY0; instead of KY2;. What am I missing? I always get KY0; as a response. 73 Kevin w9cf _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Kevin;
This tends to be a confusing command to many people. I have found that using the extended response format provides better information than the basic response, allowing the K2 to better throttle data coming from the computer. Let's take a look at your examples: On Jan 23, 2007, at 9:15 PM, Kevin Schmidt wrote: > I have been trying to use the computer control for my K2/100. I am > using the > RS232 port on the KPA100.

Actually, if the K2 is sending a character, it has already pulled it from the buffer, so the buffer is not full. You can then send one character to the K2 and should see a KY1; response. This really doesn't provide very good information for the computer, though. Thus you probably want to send the K2 a K22; command to place it in extended response mode. You will then be able to send characters to the K2, then watch the buffer as it empties. In fact, to get a KY2; response, you must be in extended response mode. It is then realtively easy to have the computer send characters to the K2, then monitor the buffer level, sending more characters when the level drops below the 75% threshold.
