Common symptoms may be: % copycat .ttyco .ttya Error opening tty .ttya, aborting. or % /usr/sbin/getty 8bit.38400 .ttya getty: .ttya: I/O error The first thing to check is that the following GNO serial port drivers exist: /dev/modem /dev/printer Next, ensure the following two lines are in your /etc/tty.config file, and that they are uncommented: modem 2 .ttya printer 1 .ttyb Finally, ensure that SIM (the Serial Interrupt Manager) is present and active. This is an init in your system.setup directory: */system/system.setup/sim Remember to reboot your system if you’ve made any changes in or to comply with the above requirements.
