comm problem with Debian Stretch

[dasyar]

Below is a test program to print out incoming data. All that I am getting is blank lines, although the cursor does move along.

I checked out if I have a real connection with GTKTerm, and that does print out the data that I am expecting. Since this is running on the new Debian Stretch version of Linux, I am now wondering if something got changed, and freeBasic input# command is not responding correctly?

Thanks
