Subject: Support for hispeed serial ports
Date: Thu, 8 Nov 2001 22:50:39 +0100 [thread overview]
Message-ID: <20011108225038.A3092@elf.ucw.cz> (raw)
Hi!
This is lying on my hdd for around forever. I used to have it in
kernel, but tytso convinced me to push it into userspace. Could it be
merged into setserial?
