I mean this one:

Do you think, or better have a URL explaining if someone attaches such
a cable to a compromised PC and a brand new notebook that a trojan
is capable of reaching the notebook? These cables work with CoolTerm
for example, where a user sees how many bytes will be transferred.

If the answer is yes, what about audio cable data transfers, which are
much slower (baud rate wise)?

If again the answer is yes too, than encrypted fax communications in
a copy shop are the better option, at least for Bob to acknowledge
the data reception from Alice, so that she knows that Bob received
the data.
