There is probably generic code available that does this. Keep in mind, you'll need an app to integrate all this data into. Plus, there may be lots of failsafes built into the software. It's wuite a large undertaking. You really aren't likely to find any cut-n-paste code to do that for you. The most you may find is serial port code. Maybe a local bookstore with an extensive windows programming section would be of help. But then, of course, you have to start with windows programming. That's an entirely different monster altogether. ;-) On Tue, 9 Nov 1999, Joss Roots wrote: >Hi there. >Thanks very much foor your reply. >I'll try to contact the Tech assistance >and will look into their user manual >and may have a chat with our maintenance people > >meanwhiles, your answer seams to be coming from >a pro, so I might need your help later on. >By the do you have any working code doing >the things you described. >thanks again. > >--- Michael Rothenberg ><rothenberg@automationonline.com> wrote: >> the following is not really related to FreeBSD: >> >> The first thing you really need to do is call >> all the equipment >> manufacturers and determine if their machines >> are capable of outputting data >> through the serial port in the first place. >> Dont waste your time if they >> dont even have the capability to squirt info >> out the ports.
