Dial-UP ISP Nachbau

Thanks to dogemicrosystems.ca/wiki/Dial... and bugs.launchpad.net/ubuntu/+so... OS: Lubuntu 32 bit 16.04. FritzBox Cable model with 2 analog phone sockets. Internal phone numbers **1 and **2 are used. Not all modems answer incoming call properly; the modem used here does so without any specific configuration. The modem is attached to the RS232 port on an older Dell laptop PC.
