    The R0| means that it was a response to command C0|, not that it was successful. 50001000 appears to be an SL_RESP_UNKNOWN error, see http://wiki.flexradio.com/index.php?title=Known_API_Responses. This might be because you are always sending the same command number of 0. It should be incremented each time you send a command. I can't see anything else that might be wrong with your command line.

    PS: I see you added more information while I was researching and typing my response. This new info leads me to conclude that the problem is definitely the fact that you are not incrementing the command number.

    Thanks! I also wrote a routine which finds every send command in the xxxx.cs api files and writes those lines to a text file with the same name as the api file with a different extension so that makes life easier also.

    John where can I find the messages.h header file referenced on the wiki ... I have not located it in the api files?

    I don't know, sorry. It's probably not very helpful anyway - what you really need to get your head around is the command/response structure. You may find that my API primer helps (see the Wiki front page).

    Wayne,

    I don't see anything obviously wrong with your command.  I just booted up my 6700 and connected via telnet and did 'slice c' (create a Slice) then 'slice t 0 14.245'.  This tuned the Slice as expected.

    The only reasons I can think of for getting that response (0x50001000) would be either that Slice 0 (displayed as A) doesn't exist or there is some kind of syntax issue with the command.

    Found out the issue I was having resulted from me not adding a vbcrlf to the command when sending it using vb6 so there was for some reason a delay in it being sent out by the winsock control I was using. All is great now and sent immediately. Thanks!
