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://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
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:
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
