Is anyone here familiar with qbasic programs and specifically programs using com ports? I'm trying to run the attached program in dosbox but whenever it gets to the OPEN COM1 line it fails with a device timeout error.
I get the same error even on a physical pc running dos, and the serial port is set up properly in dosbox.
I think the issue is that the device I'm trying to connect to doesn't send any data through the serial line unless the right command is sent to it, and I think basic is waiting for a response or something which it doesn't get. If anyone knows how to configure the program so it doesn't wait for a response before continuing, or if there is actually some other issue, I'd really appreciate the help.
The program is from this scientific paper: https://sci-hub.se/10.1016/0010-4825(93)90144-P, and I know the serial device works, if I send commands to it over realterm it responds correctly.
