Hi all,
I get the following message:
tts/0: 1 input overrun(s)
each time while downloading pictures from my digital camera via ttyS0,
_and_ switching between an X session and textmode console.
(ie, 1 switch -> 1 error)
This is with 2.4.1. I don't remember getting these with 2.2
This error also means a transmit error (gphoto reports error and a packet
has to be retransferred.)
What is this? Why I'm getting it? What should I do? :)
bye,
Balazs Pozsar.

I don't think this should be normal.
The relevant dmesg part:
Serial driver version 5.02 (2000-08-09) with MANY_PORTS SHARE_IRQ
SERIAL_PCI ISAPNP enabled
ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS01 at 0x02f8 (irq = 3) is a 16550A
I am using 115200.
