What port is the echo test program expecting to use?  Is it the echo
program from solivant.com.  That one is port specific.  Altairs don't
always match non MITS cards by default.  If you're using an echo test
program be sure you have the correct port (octal 0 , 10, 20, etc.) .  I'd
try using a known working serial card if you have one, first.  You can
bring your altair to kennett classic if you want. I have four altairs here
set up at the moment.  Please contact me privately if you plan to come up,
safety rules for COVID, etc.
