[comp.sys.mac.programmer] Set serial speed > 57,6Kbaud

boortz@sics.se (Kent Boortz) (04/26/91)

I want to set the speed above 57,6Kbaud on the serial port.
I can't do it with SerReset. Device Manager control call
13 takes an unsigned short so I can't use that.

How do I do it (it is possible, isn't it?). Are there different speed
limits on different members in the Macintosh family?

I really want to set 153,6Kbaud and 250Kbaud. If I can't use the
internal clock but the hardware can handle the speed with an external
clock, how do I calculate the clock speed needed?
