modems and Model 735

[Dan Koehler]

I 'inherited' an old HP 735 at my new job. It has some interesting ports on the
back labeled 'line in', 'line out', 'phones'. I would like to be able to play around
with some telephony stuff but I cannot find documentation anywhere on what
these ports are for and what they are capable of. Can anyone help me?

Hi,

the ports you've listed are for audio devices: line in/out for audio input/output.
phones is for connecting a head phone (not e telephone) to hear audio from files.
You could check this program:
/usr/audio/bin/audio_editor (HP-UX 9.x) or
/opt/audio/bin/audio_editor

Off the top of my head man aserver and man audio may have some info ?

also found following :

The backpanel of 735 is like
PHONES LINE OUT
(O) (O)
KYBD
HP-HIL SPEAKER MIC LINE IN
| | (O) (O) (O)
+-+
If I connected my external speaker to either PHONES or LINE OUT,
send_sound will generate a sound even under SPEAKER=ex environment
was set. On the other hand, if I connected a speaker to SPEAKER,
send_sound won't generate a sound under SPEAKER=ex, but generate a sound
without SPEAKER environment. This confirms me that "external" outputs
are "PHONES" and "LINE OUT", and "internal" output is "SPEAKER", so that
if user set SPEAKER=external, and no speaker connected to "external"
output, any sounds will not be generated.

use send_sound command to test (also comes with a man page).

You would need a serial port if you plan to hook up a modem. In addition to the audio ports, are there any additional ports? I believe that particular model will be specific as to where the serial port would be.

I just got done playing around with lineout and audio_editor on a s700 c200 ws. audio_editor has to be loaded from the hp application cd's. you must load netscape fasttract first and then HP MPower//Web for Series 700, and MPWeb2.0 s700 reference bundle. linein can be used to hookup a cd player to record some music and audio_ut hookup to external speakers. (/opt/wt/bin/audio_editor )
