I can't get MITS package II to respond to user input. I have loaded it (several times) from the cassette audio image, carefully following the instructions in the ReadMe PDF. I have also loaded it from the .TAP file using the 2SIO loader. I successfully get two spaces with a "?" prompt. It sure looks like it is working. However, no keyboard input of any kind gets echoed back. Nothing happens when I send a <CR>. (No new prompt shown, it looks like the <CR> is being ignored.) I have the terminal setup for 7 bits with space parity. The machine looks like it is in the right state. When I follow the instructions for restarting the monitor everything works as expected. I get a new " ?" prompt. However, all user input is ignored.
Can anyone recommend what I look at next? I am using the default TeraTerm settings from Mike. I am only adjusting the serial settings when I am supposed to be, according to the instructions.
