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

I maintain a VMS real-time app. that has a serial interfaces to

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.

Determine whether you have to work at the Ethernet level, TCP/IP
level, or some other protocol level to talk to the analyzers. TCP/IP
is the most likely.

Read either the I/O Users Guide, or the TCP/IP programming manuals to
figure out how to do this.

Then rewrite (or at least modify) the code.
