Subject: [PATCH] [2.5] adding ppp xon/xoff support
Date: Fri, 11 Jul 2003 21:17:16 -0400	[thread overview]
Message-ID: <20030712011716.GB4694@bouh.unh.edu> (raw)

Hi,

This patch wasn't applied, probably because the misplaced else
statement, here is a corrected version. This would at last make linux
support xon/xoff for ppp connections (it hasn't been available since 2.0
at least).

Please apply,

Regards,
Samuel Thibault
