Problem: bdtab_norm[] above specifies { CLK_RTxC, 24 } for 9600 baud. This doesn't make sense. Perhaps the logic in SCC_ioctl() in Atari_SCC.c fixes it up for speeds specified by the user? Who knows.That ends up using time constant 10 and mode 16 as per your calculation for 3.67 MHz clock input - 9562 baud instead of the 9680 possible from the 8 MHz clock.
Yes, I see now. This code is confusing.
I might have misunderstood something - would really want to check that using a scope. Both appear to work OK, so no matter really.
And besides, there's no need to change the baud rate until someone #defines USE_SCC_[AB] and then gets annoyed with 9600 baud. -- -- To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
