Running a loop back test for throughput using a program we have here ttyS0 fails. Plugging in SuSE 10 and running the same test it passes. FC 2.6.15 includes the new tty layer changes made by Alan while SuSE 10 still uses the old. Has anyone else experienced this? thanks, Kevin - To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
