SubjectRE: what serial port type are Elan ports?
Date
Hi Alex,

Yes, it is exactly what I was looking for. Thanks very much.

Robert Schwebel has indicated that the Elan silicon bug is also in the SC410
chip. If you or somebody else have a ready to run SC4X0 based system, please
send me the first ten or so lines of output from the following command so I
can see the UART type that was detected for the SC4X0's serial ports:

more /proc/tty/driver/serial

Thanks again,
Ed
