Bloody Verizon. > This strikes me as being some damn petty politics on verizons part. I'm a customer because its the only game in town with affordable broadband, by at least 30 dollars a month. So I'm stuck with it, or a friggin dialup that is also about 30 a month more expensive. And it seems that everytime I use the "reply all" button on this list, I'll get at least 2 bounces because somebody elses server has blacklisted verizon for running an open relay 2 years ago, & never got around to lifting the ban when verizon rebuilt the systems last spring. One should be carefull as that shoe can fit many feet. The CC: line of this message: Jim Nelson , Russell King , Andrew Morton , kernel-janitors@lists.osdl.org I'm curious as to who I will get a bounce from. >Documentation/serial/driver mentions a reference implementation - > serial_amba.c.
