34401A上的USB转RS232适配器无法相互通信

我的办公室有2台电脑第一台电脑使用WinXP，主板有RS232端口第二台电脑使用Win XP，主板无法插上RS232。
我使用ATEN USB转RS232适配器连接到34401A第一台计算机可以毫无问题地连接到34401A。
只需安装Benchvue并使用RS232电缆连接它们。
但这款电脑配置不好，它采用双核处理器，512MB Ram，所以操作速度很慢。
第二台计算机配置更好。
但由于它没有配备RS232端口。
我使用ATEN USB转RS232适配器连接PC和34401A。
但是当我尝试在Benchvue中启动DMM应用程序时，PC和34401A都无法相互通信。
并且34401A前面板“ERROR”指示灯亮起。
我想这个问题的出现是因为USB转RS232适配器不支持某种握手。
我的问题是，是否有任何品牌和型号的USB转RS232已经获得KEYSIGHT认可，可用于其万用表产品？
谢谢

  My office have 2 computers
first computer use WinXP, motherboard have RS232 Port
second computer use Win XP, motherboard cannot plug in RS232. I use the ATEN USB to RS232 Adapter to connect to 34401A

The first computer can connect to 34401A without any problem. Simply just installed Benchvue and use an RS232 cable to connect between them. But this computer config is bad, it is using dual core processor, 512MB Ram, so the operation is very slow.

The second computer had a better config. But since it does not come with RS232 Port. I use ATEN USB to RS232 Adaptor to connect between PC and 34401A. But when I try to launch the DMM apps in Benchvue, both PC and 34401A cannot communicate with each other. And the 34401A front panel "ERROR" light is on. I guess this problem occur because of the USB to RS232 adapter do not support some kind of handshaking.

My question is, is there any brand and model of USB to RS232 that are already approved by KEYSIGHT that can be use on their multimeter product ? Thanks
