And how will he get the Terminus application on to his Amiga :roll:
@wlfrancis
There are very few options unless you have the capability to send at least some small software to your Amiga first.
The easiest option is to mount the PC0 mountlist on your Amiga, insert a floppy disk, and format PC0. This disk will then be read/writeable in both the Amiga and a PC. So you could put the disk in a friend's PC to put a terminal application on it, and then copy it to your Amiga.
The second option if you can't find a PC with a floppy drive is
here. It involves writing an Arexx script which will receive a file through the Serial port. You don't have any way to copy the script to your Amiga, so you would have to type it in. The problem here is that you have to run a piece of software called ADFSender on a PC to actually send the file. I don't know if there is a Mac alternative.
Hope this helps.
