无法在VEE中使用COM 3

我的电脑没有USB端口所以我今天早上安装了CP210X USB到UART板，系统将它分配到COM 3端口并使用了Windows 2000中已经提供的任何驱动程序。将它与HyperTerminal或命令提示符一起使用，
一切皆好。
我通过COM 1和COM 2进行通信的现有VEE程序仍然可以正常工作。
但是，我无法在VEE中使用COM 3，我只得到“配置错误”消息。
我已经通过I / O仪器管理器正确设置了所有可以设置的参数，但仍然没有乐趣。
我想我错过了一些司机设置程序？

  My PC had no USB ports so I installed a CP210X USB to UART board this morning and the system assigned it to the COM 3 port and used whatever driver was already there courtesy of Windows 2000.  Using it in conjunction with HyperTerminal or with Command Prompt, all is fine.  My existing VEE programs communicating over COM 1 and COM 2 still work fine.  However, I can't get anything to work with COM 3 in VEE, I just get "Configuration error" messages.  I've correctly set all the parameters I can set via the I/O Instrument Manager, but still no joy.  I guess I'm missing some driver set up routine?  Any suggestions?Ivan Edwards ---You are currently subscribed to vrf as: [email=r***@soco.agilent.com]r***@soco.agilent.com[/email]To subscribe please send an email to: "vrf-request@lists.it.agilent.com" with the word subscribe in the message body.To unsubscribe send a blank email to "leave-vrf@it.lists.it.agilent.com".To send messages to this mailing list,  email "vrf@agilent.com".  If you need help with the mailing list send a message to"owner-vrf@it.lists.it.agilent.com".Search the "unofficial vrf archive" at "www.oswegosw.com/vrf_archive/".This e-mail message is confidential and for use by the addressee only.
