To do this with windows would probably always be messy because you cannot guarantee the timming to the port. What you might want to explore is building a simple hardware interface wuit a BasicStamp microcontroller www.parallaxinc.com and interface it to your serial port for control messages...
I'm not shre how to send you the program, but I was able to whip up a Visual Basic version that utilizes MSCOMM. It compiles to a small binary that only sends your specified string out com port 1 and ends.
It basically is only one module but there must be a form to contain the MSCOMM control...
Yes, if you will email me I'll send C or Basic code to do this.
Endian is an expression comming from the difference between how data is actually stored in the RAM memory by the Intel uProcessor vs how the same data is stored by other type uProcessors, such as the Apple computer. The memory...
One significant problem with a long run of continuous copper is the extreme likelyhood of surges being induced by near lightning. This condition is present everywhere and should not be overlooked. If the owner needs point to point control then a fiber optic link should be considered.
If a line...
Probably the least expensive and most reliable control system would be induction relays and electrodes similar to the B/W 1500 series. B/W is now owned by AMETEK. This type control equipment has been around and not changed much over the years. It is easy to design and install and it is very...
