From 916d15445f4ad2a9018e5451760734f36083be77 Mon Sep 17 00:00:00 2001 From: Karsten Keil Date: Mon, 26 Jun 2006 20:21:01 +0200 Subject: [PATCH] [PATCH] fix processing of the last byte in isdn_readbchan_tty() The changes in the tty handling contain a bug while accessing the last byte in the skb. Since special sequence for control of DTMF and FAX via ttyI* devices handled via this path, these services do not work anymore.
