asterisk users - Oct 2003 - modem connection over handy?

Hi all,

does anybody know if it is possible to make a modem connection (voice)
through * over a handy which is connected to the RS232 port ?

I get following messages when * starting:

WARNING[16384]: File chan_modem.c, Line 356 (modem_setup): Modem reset
failed: (No Response)
WARNING[16384]: File chan_modem.c, Line 735 (mkif): Unable to configure
modem '/dev/ttyS0'
ERROR[16384]: File chan_modem.c, Line 871 (load_module): Unable to register
channel '/dev/ttyS0'
WARNING[16384]: File loader.c, Line 301 (ast_load_resource): chan_modem.so:
load_module failed, returning -1
WARNING[16384]: File loader.c, Line 347 (load_modules): Loading module
chan_modem.so failed!

Thanks for help,

Thomas.
