Do I have to gink with > uugetty or set serial? Is that the right place to look?? Ric The IRQ won't show up unless something is on the serial port or using it. For example, my machine shows this normally: 0: 1668 IO-APIC-edge timer 1: 163398 IO-APIC-edge i8042 6: 6 IO-APIC-edge floppy However, if I "agetty -L 9600 ttyS0", it shows this: 0: 1668 IO-APIC-edge timer 1: 163146 IO-APIC-edge i8042 4: 25 IO-APIC-edge serial 6: 6 IO-APIC-edge floppy So, you need to look at it when the modem's active (or you've spawned something like agetty on it). ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxx - - CDN Systems, Internap, Inc. http://www.internap.com - - - - Never put off 'til tommorrow what you can forget altogether! - ----------------------------------------------------------------------
