Summary:                    [patch] v.110 dialin support for ISDN channels
Description: 
Many years ago I wrote app_v110.c for use with mISDN channels. It was
included in the Beronet app_bundle which I thought they were going to
submit after chan_mISDN was merged:
http://www.asteriskguru.com/archives/asterisk-dev-re-chanmisdn-in-asterisk-beta-2-vt60496.html#170458

Someone's now made it work with Zap channels too, and is asking why it
didn't get merged.

I'll attach my original code for reference and state that I have a
disclaimer on file. Hopefully I can let the person who ported it to Zap
take care of submitting an up to date version which is tested with current
Asterisk code.

I tried app_v110.c.trunk-rev-196585 against asterisk-be-C.2.1.2 (this is
almost a modified asterisk 1.6x I think)


I adapted added some debug, but the STDOUT doesnot map to STDIN of pppd
(can pppd handle piping ? Or must you provide an pseudo-TTY?)

I added the source app_v110_td.c
