FS-UAE includes emulation of the Amiga serial port. The emulation is at least good enough for debugging purposes.
You can specify an IP address and a port to listen to, and FS-UAE will create a TCP/IP socket for the serial port. You can then connect to this socket to read from / write to the emulated serial port.
To listen to port 1234 on localhost, you can use the following option:
serial_port = tcp://127.0.0.1:1234
It is also possible to have FS-UAE wait during boot until you connect to the serial port socket. This is useful in order to be sure to capture all the serial port output. Append /wait to the option value to enable this:
serial_port = tcp://127.0.0.1:1234/wait
On Linux and OS X (and other Unix-like systems, probably), you can use the following option to emulate an Amiga serial port using a real device:
serial_port = /dev/something
Note: I haven't tested using a real serial port, so I don't know if that'll
actually work. But what have been tested is using a tool like
create virtual devices. For example, you can run something like this:
socat pty,raw,echo=0,link=/tmp/virtual-serial-port -,raw,echo=0
And then set up FS-UAE to connect to this:
serial_port = /tmp/virtual-serial-port
If you have configured a virtual serial port using
socat like in the
above example, you should be able to run the following command from within
In your host terminal you should see the CLI prompt and you can start using this host-based Amiga shell.
Note: You may need to first enable the aux device within AmigaOS. To do this, copy or move the
