After running a perl script to dial my ISP, I get an error message
after about 60 seconds of connection

ttyS: 1 input overrun(s)

Then my external modem disconnects. My modem is /dev/ttyS0.

/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
        Baud_base: 115200, close_delay: 50, divisor: 0
        closing_wait: 3000
        Flags: spd_normal skip_test auto_irq

/dev/ttyS2, Line 2, UART: 16550A, Port: 0x03e8, IRQ: 4
        Baud_base: 115200, close_delay: 50, divisor: 0
        closing_wait: 3000
        Flags: spd_normal skip_test

There are two more ttys using IRQ4. It would be nice to have just one
port (the modem) using IRQ4--is that possible?

I noticed /dev/ttyS2 is also using IRQ4 (is that OK?) I have a scuzy
hard drive. My ext modem is connected to serial COM1. Nothing
physical is connected to COM2. My UART is on the motherboard. As
root, I tried to install IRQTUNE, but the make install failed after
writing out the object modules (the irqtune file is there, but won't
execute -- even with -rwxr-xr-x). I have a sound card, but I can
remove it.

Anyway, there some simple fixes for the input overruns? There's lots
of (confusing) material about this subject.

Thanks.

I'm using Fedora Core 1.
