Project 3 [WIP]: Lenny Troll (phone anti-scammer bot) Sources: https://lennytroll.com/ DIY guide highly recommends U.S. Robotics USR5637 USB Modem Modem Requirements: On-board harware controlled modem, "softmodems"/winmodems not supported. Must have voice capability (TAD/TAM capability) Another modem option: StarTech USB56KEMH2 USB Modem, uses Conexant CX93010-21Z chipset (not verified). Check out USB info before installing lenny: Is the USB modem a serial device (eg, /dev/ttyUSB0 or /dev/ttyAMC0)? Should "just work" with Linux. Sending AT commands to serial modem in linux (test that the modem works before installing Lenny) lenny_service.txt (systemd service file) will have to be edited to point to the correct directory housing Lenny Troll.
