请问有IO库的开源替代方案吗？

我正在努力了解所有这些不同的通信内容 - VISA，SCPI，IVI等。我想知道，有没有安捷伦IO库的开源替代方案？
我的意思是，这些库只是简单地围绕VISA标准，就像IVI围绕VISA一样？
你可能会注意到，我有点困惑。
但无论如何，要专注于一个问题 - 是否有安捷伦IO库的开源替代方案？
要使用像PyVisa这样的包装器，我仍然需要依赖IO Lib ...我可以选择不使用安捷伦的IO库吗？
我也在考虑使用Javascript创建一个独立的SCPI脚本编写器。
我的目的是能够将我的javascript文件带到任何PC，并开始发送SCPI命令，而无需担心PC是否有IO库 - 我会提供自己的独立库。
那可能吗？

  I'm trying to understand all these difference communication stuff -- VISA, SCPI, IVI, etc.

I am wondering, is there an open source alternative to Agilent IO Libraries?  I mean, these libraries simply wrap around VISA standard, the same way IVI wraps around VISA too?

As you might notice, I'm a bit confused.

But anyway, to focus on one question -- is there an open source alternative to Agilent IO Libraries?  To use wrappers like PyVisa, I would still need to depend on IO Lib ... can I choose not to use Agilent's IO Libraries?

I'm also thinking of creating a self-contained SCPI scripter using Javascript.  My intention was to be able to bring my javascript files to any PC, and start sending SCPI commands without needing to worry if the PC has IO Libraries or not -- I would provide my own standalone libraries.

Is that possible?
