FDB:(Kenwood)/ command 'getstat' takes par;
Sqlog/ table of 'issue' didn't get version number;
modify verbose display;
add key 'label' to the echo frame;
correct response protocol;
Stream:/ try to use IO.readpartial(), which uses buffer and nonblock if no data.
     * Kenwood often gives response of partial strings (tail is cut off) and gives the rest at next reading.
Exe#exe()/ help list had added unnecessary str (command);
