NI-Device with RS-232

[Alain 23]

1- I try to understand how i can implemented RS-232 with the NI-Device Kit. The documentation tell that IEEE-488.2 is not specific to GPIB. Does NI-Device Kit can be modified to support RS-232?
2- I want to know if the communication bus must be implemented in Kernel mode or can be implemented in user mode?

I am sorry, but currently NI-Device does not have support for RS-232. It currently only supports GPIB.

The documentation is correct in that IEEE 488.2 is not specific to GPIB and can be implemented on top of other buses. There is a current specification (IEEE 1174) which describes how to implement IEEE 488.2 on top of RS232. If NI adds support for RS-232 in NI-Device, it will likely follow the IEEE 1174 protocol. Being a serial interface, it would only require user-mode pieces.

I will add RS-232 to the list of requested interface buses for future versions of NI-Device. Any information you can provide regarding your desired use would be helpful.
