They merged with Studebaker somewhere around 1950, and Studebaker-Packard later merged with Nash-Willys-Hudson to form American Motors. The last traces are now embedded in Diamler-Benz, as Chrysler-Diamler. A 1930's Packard is a thing of beauty.

I found that the compiler made a huge difference on PICs, FWIW. Serial comms got tamed tremendously by CCS. -- Scott Reverse name to reply

It is commonly regarded as worthless, and is regularly the cause of problems. I don't want to start a religious war over which is the "best" terminal emulator program, but you should download Tera Term Pro. It's free, it's simple, it's reliable, and thus it is far better than hyperterminal. If you ever want something more advanced, there are lots of options (and even more opinions), but at the moment, TTPro is your best choice.

Also, it is a part of the evil empire of MS, and every true believer should never even think of it. However I don't know of any specific problems of hyperterm. If all that you need is a basic terminal, it will work as good as any other program. Vladimir Vassilevsky DSP and Mixed Signal Design Consultant http://www.abvolt.com
