Re: [openrisc] [PATCH] Would you like to have UART0 in a xterm ?

[Marko Mlinar <markom@opencores.org>]

Great work!
I like your solution very much!

Is it possible to add functionality for txfile and rxfile:
when they are defined and channel variable is not defined,
channel variable is generated?

Is it possible that you commit the patch?
If you have registered to OC, you already have CVS write access.
