This is a port of OpenBSD's serial terminal emulator cu(1) to Linux.

Portable cu(1) is built using cmake. It requires a working C compiler, standard library and headers and libevent.

mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make

Pre-built binary packages for opencu are available in Debian, Ubuntu and the Arch User Repository (AUR). It is our hope that packagers take interest and help adapt opencu to more distributions.

To connect to the serial port at /dev/ttyUSB0 with a baud rate of 115200 baud:

cu -l /dev/ttyUSB0 -s 115200

To close the connection and exit cu, enter ~.. You can use ~? to print a list of all supported commands.
