Hello, After googling for awhile I came across a unix command serreset It is supposed to communicate with the serial port driver and I would have been able to do like: serreset 9600, n, 8, 1 Or something like that. But my mac os x 10.6 machine running snow leopard does not support this command I tried reading serreset's man page and my computer said that a man entry wasn't available. I was excited when I found the article on the mac website, the article was from 2007. I wonder when this command stopped being used? I have time machine on my computer, maybe I could look back and try to find it? But I don't know where to look? Also I wondered if there was a similar program I could use, or if there was a way to somehow get the source code and install it?
