How to set uart1 up for 100000 baud or any other no standard baud rate?

Hello,

Using DM355 wtih 2.6.28, would like to use uart1 for serial communication at 100K baud, how would I go about doing that? could someone point me in the right direction as to what files I would need to modify?

I believe this information is passed to Linux Kernel via u-boot bootargs variable (e.g. console=ttyS0,115200n8 )

It only accept the normal standard bauds (ie 9600, 115200, ..). consol is using ttyS0 at 115200, i would like to use "/dev/tts/1" at 100000, is there a way to set the baud other than the bootargs which do not accept that speed.

I believe this is a limitation of the RS232 standard, which the driver incorparates. I would start by looking at the Linux driver to see if it supports non-RS232 standard baud rates; if it doesn't you may need to add the support yourself.
