Found this in sio.c: static struct speedtab comspeedtab[] = { 0, 0, 50, COMBRD(50), 75, COMBRD(75), 110, COMBRD(110), 134, COMBRD(134), 150, COMBRD(150), 200, COMBRD(200), 300, COMBRD(300), 600, COMBRD(600), 1200, COMBRD(1200), 1800, COMBRD(1800), 2400, COMBRD(2400), 4800, COMBRD(4800), 9600, COMBRD(9600), 19200, COMBRD(19200), 38400, COMBRD(38400), 57600, COMBRD(57600), 115200, COMBRD(115200), -1, -1 }; So I guess 115.2kbps is as fast as the sio driver will do. > > Doug White | University of Oregon > Internet: dwhite@resnet.uoregon.edu | Residence Networking Assistant > http://gladstone.uoregon.edu/~dwhite | Computer Science Major > > Nadav
