I guess not. 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.
