I have got hold of the manual provided with my modem. I am perusing
the manual for the past half an hour or so, but am not very sure about
what to look for. There is no mention of mike anywhere in the manual.
(But there are a handful of commands for the speaker.)
I am quoting here two appendices from the manual, which I think might
contain the relevant information. Could you please help me to figure
out, which of these AT commands are for the mike? Or is the relevant
information not available in the quoted text?
If any of you think that you can help me with this, kindly let me
know. I'll send you the entire manual in PDF off-list (260384 bytes).

Appendix 2 AT command set
Executing commands
Your modem is in Command Mode upon power-on and is ready to re-
ceive and execute AT commands. The modem remains in Command
Mode until it makes a connection with a remote modem. Commands
may be sent to the modem from an attached terminal or a PC running a
communication program. This modem is designed to operate at com-
mon DTE speeds ranging from 115.2 Kbps to 300 bps. All commands
and data must be issued to the modem using one of the valid DTE speeds.
AT commands and format
All commands must begin with the AT prefix, followed by the command
letter and ended with the ENTER key. All default settings are printed in
bold text. Spaces are allowed in the command string to increase com-
mand line readability but are ignored by the modem during command
execution. All commands may be typed in either upper or lower case,
but not mixed. A command issued without any parameters is considered
as specifying the same command with a parameter of "0".
Example: ATL [ENTER]
This command causes your modem to lower its speaker volume.
AT Command Summary
All default settings are printed in bold and italic text.
