Can Listen; Cannot Talk

Can Listen; Cannot Talk

[G Anna]

Dear All,

I have an external modem.  It has, apart from the telepone plug and
the power plug, two plugs - one for speaker and the other for a mike.
I have connected my head-phone/mike to this.

Using minicom (with the help of AT commands) I am able to dial another
phone.  The phone rings at the other end.  When they answer the phone,
I can listen to their voice.  Its very clear too.  But they are not
able to hear my voice.  Can anybody help me understand why this is so?

Am I doing any silly mistakes anywhere?  Kindly help me.  Pointers to
relevant information would also be very helpful.

$ : using RH 7.1
$ uname -a
Linux wobble 2.4.16 #8 Tue May 14 14:15:58 IST 2002 i686 unknown

Thank you for your time and effort.

Cheers,
anna

Might wanna make sure 1) that your modem is full-duplex capable adn 2) that it
is set up in that mode.

This does not sound like a Linux problem. To have any hope of getting
specific help, I think you'll need to tell us the manufacturer and model
number of the modem (and the URL of its manufacturere, if you happen to know
it). 

You *probably* have to send the device some non-standard AT command to
enable the mike for input (there's a standard AT command that turns the
speaker on and off), but that's just a guess.
