Re: Converting serial I/O to ethernet I/O

I maintain a VMS real-time app. that has a serial interfaces to
analyzers. The latest version of the analyzers support network
communications and we want to convert from serial to network.

Any pointers on how to do it? I think it's a matter of making the
right QIO calls, perhaps
just revising or adding alternative QIO calls.

It is not that simple. The first question is: what ethernet protocol do the
analyzers use? Most likely it is some sort of TCP/IP. Then you need to use
the routines of the TCP/IP stack in use.
