Works with umodem.c:1.53, umodem_common.c:1.3, umodemvar.h:1.2 when You
connect the phone after boot.

I just figured out that it will not work when you boot up with phone already
connected. It detects everything but I don't receive any answer for AT.
Same problem is exists with Your and my patch.

I think it is very hard to repair without hardware so I think You may close this
ticket for now and I'll try to find out what goes wrong.
