FS-UAE Amiga Emulator


Serial port

FS-UAE includes emulation of the Amiga serial port. The emulation is at least good enough for debugging purposes.

Enabling TCP/IP serial port

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://

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://

Connecting to a serial device

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 socat to 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

Getting an Amiga shell in an external terminal

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 the Amiga:

newshell aux:

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 AUX icon from Storage/DOSDrivers to Devs/DOSDrivers.
