No, I don't have modem there, I tried to connect Apollo only (test 1)
and both Apollo and braille terminal - Alva (test 2) which is usual
setup.

This information about handshaking may be misleading because I received
it from my colleague who purchased Apollo whom I asked for advice in the
first place and he was able to tell me more.

Ah, I see. It's always hard to make buggy hardware work. More praise on
you for trying to do so! :-)

And how can I do it - is there a command which could make Apollo to say
or to return the ROM version?
