modemu2k
Hayes-style AT-command modem emulator bridging serial-style I/O to TCP/Telnet
modemu2k is a Hayes-style AT-command modem emulator bridging a serial-style interface to TCP/Telnet ("dials" out and answers incoming connections). It ships as a C library (libmodemu2k) exposing the modem state machine, plus a small CLI built on top that allocates a PTY and either reads stdin/stdout directly, forks a comm program (minicom, picocom) on the slave, or accepts an incoming TCP connection as the TTY. IPv4 and IPv6. modemu2k is based on modemu, originally developed by Toru Egashira. This package contains the CLI binary and the m2k-minicom / m2k-picocom helper scripts.
