在本地USB棒上保存波形语法错误

我正在使用一套DSOX3SGM，分段存储器应用程序，用于3000 X系列示波器，由基于LabWindows的DAQ系统远程操作。
由于从所有示波器通过TCP / IP连接传输数据需要很长时间，我想将波形保存到我放在示波器上的相应USB驱动器上。
我可以手动完成。
但是，我想通过我的程序中的远程应用程序来完成它。
我使用以下语法:: SAVE：WAVeform：FORMAT ASCiixy：SAVE：WAVeform：LENGth max：SAVE：WAVeform：SEGMented ALL：SAVE：WAVeform：STARt \ u***  test.csv我的前三个命令成功执行，但第四个命令执行
永远不会工作
它说INST错误-101，无法识别的字符。
我正在使用C编码，我甚至printf我发送的命令，所有不同的选项，但没有成功。
请帮助我，我知道我在做一些愚蠢的错误。
非常感谢您的帮助。

  I am using a set of DSOX3SGM, Segmented Memory Application for 3000 X - Series Oscilloscopes remotely operated by a LabWindows based DAQ system. Since transfer of data from all the oscilloscopes through TCP/IP connection takes long time, I want to save the waveforms to the respective USB drives I put on the scopes. I can do it manually. However, I want to do it through remote application in my program. I used following syntaxes:

:SAVE:WAVeform:FORMat ASCiixy
:SAVE:WAVeform:LENGth max
:SAVE:WAVeform:SEGMented ALL
:SAVE:WAVeform:STARt \u***test.csv  

My first three commands executed successfully, but the fourth one never working.
It says INST Error -101, unrecognized character.

I am using C coding, I even printf the command which I sent, all different options, but no success.

Please help me, I know I am doing some silly mistake. Thank you very much for your help.
