话带数据中传真解调程序

Using your modem as a phone with ltmodem.
=========================================

The following is a compilation of information supplied by Pavel.

The file phone.c contains code to phone over ltmodem. It is rather
nice intro on how to use ltmodem's interface. It also actually does
something usefull: you can call through it!

In phone.c there is program called phone. Together with ltmodem and
linmodem programs, it can act as telephone over lucent
winmodem. I.e. you sit down, put headphones and microphone on your
head, and type ./phone. Then you hear dialing tone so you type "dial
martin". phone looks up martin in your telephone directory and dials
right number. Then you talk (and you can do commands like record
/tmp/file.to.record.talk.in), then you quit and machine hangs up.

It is not good telephone because theres some non-trivial latency in
there, but it is usable.

The available commands are:
  "dial", "Initiate call to given number"
  "?", "Synonym for `help'"
  "help", "Give some help"
  "quit", "Exit program"
  "record", "Record conversation to file"
  "play", "Playback file to modem"
  "stop", "Stops playback"

                      -------------

To compile phone.c type:
 make -f phone.c  

Note that you need esound to compile it as is. Pavel used version 0.2.8
but there's nothing to stop you trying to use it with another version of
esound, though it may not work!

In the case of RedHat installations you need the esound and esound-devel
rpms installed. I have tested it with version esound 0.2.12 on a RedHat
6.0 system and it compiles OK.

You also need a ~/.phonebook file.
