From e1eaea46bb4020b38a141b84f88565d4603f8dd0 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Fri, 26 Mar 2010 11:32:54 +0000 Subject: tty: n_gsm line discipline Add an implementation of GSM 0710 MUX. The implementation currently supports - Basic and advanced framing (as either end of the link) - UI or UIH data frames - Adaption layer 1-4 (1 and 2 via tty, 3 and 4 as skbuff lists) - Modem and control messages including the correct retry process - Flow control and exposes the MUX channels as a set of virtual tty devices including modem signals. This is an experimental driver.
