>Hi,

>There is a class called SerialPort.
>You use it like that:
>|port input output|
>port := SerialPort new.
>"Here you can set up the port, check the settings protocol of the  
>SerialPort class."
>port openPort: 0. "Here you can put a number, or a string like  
>'/dev/ttyS0' in Linux"
>output := port nextPutAll: 'ATI0',Character cr.
>Transcript showln: port readString.

>ATI0 is an example of the Hayes AT commands used to control modems  
>(they are use for most modems, not only Hayes), see here:
