Hi, Jacques and MarvS, Thank you for you advices. I tried SmartLink modems. I could get /dev/ttySL0 and /dev/ttySL1. I could use both device via minicom. But SL modems cuold not detect DTMF tones. I read source code. Many voice command was not implemented yet. I thought it is cause. I'll find another way(includes HARDWARE MODEMS). Thank you. -- Honda <powered . by . the . honda [at] rhythm . ocn . ne . jp>
