Please respond only if you are able to resolve the problem: we need to connect 2 pc for a little data bitrate with audio bandwidth (wire connection). Usb/jack audio connectors. With modem client and modem server (i.e old 56k modem) or whatever... For example (but you can use other solutions): analog modem using Arduino controller. FSK enconde/decode. 2 modems wired by 2 lines. Input from Pc would be a serial over USB. Please don't respond if you don't have the capability.  Many thanks

I understood your requirements. You need to connect 2 pc by audio cable (telephone wire) for a small data bit rate. It is available in the market with ADSL modem, but I don't understand the Arduino roll here. Will you explain? 15+ years of experience on Computer Language and Digital Electronics.

Hello, I am interested to find solution for your problem. Some more clarification is necessary about bandwidth required, connection length and project delivery. As for example, 44 Khz audio data at 16 bits resolution would take about 880 kbit/sec bandwidth to transfer over serial connection. It is possible to have such bandwidth using serial to USB, but other factors might become important. I can design and prototype necessary hardware to use for connections.
