To send data i need to connect the RPi to a usb dial-up modem." "The RPi should receive the audio signals, process them and then send them through the telephone lines.
And when you say "I need to send and receive data over an external modem" we are thinking bits and bytes, not actual sound.

You will most likely also see a reference to "ttyACM0" or "ttyUSB0" which is the name of the serial device to use with any terminal program or your code. run "dmesg" and look at the bottom of the output, is will give some indication of how the kernel see your device. Make a note of the new entry in the list. Enter a name in the box under Saved Sessions, and click the Save button on the right.How do i know this? Is there a specific command to display serial devices/ports in raspbian? If you want to save those settings for later, use the options under Load, save or delete a stored session. For boards with built in USB it doesn't matter so much but for ESP8266 and other board with a separate chip, the speed required by the board is 115200 bits per second. This called the baud rate, which is the speed in bits per second that data is sent over the serial connection. In the box under Serial line, enter the serial port you found that your board is using.Under Connection type: choose the button next to Serial.However, the 64-bit version will work on most PCs. If you run into issues, you can try downloading the 32-bit version instead. Download the file and install the program on your machine. It is most likely that you'll need the 64-bit version. You'll want to download the Windows installer file. The first thing to do is download the latest version of PuTTY. If you're using Windows, you'll need to download a terminal program.
