The probing sounds like you get no interrupt at all, but since the int probing waits for unassigned interrupts the test may fail for special systems or BIOS setups. > > : Surprisingly, but it seems that both COM3 & COM4 ports work ok > > : (getty works, there is no "silo overflow" errors). > > > > That's likely because you are using 9600 baud. sio installs a timeout > > to harvest characters, and that's what saves you. > > > > > > : So, should I worry about this error? > > > > Likely. > > > > Warner > > Thanks for your help. I'll test higher speeds tomorrow. Test tranfering data at any speed and check vmstat -i output if you got interrupts for it. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
