(that's me) has a question for you/unix unanimous group.

1.  I've, successfully it appears (much to my own surprise)
    hacked SCO 386-Xenix's dialer program to do a call to
    an online service and complete a transaction. In the
    process of doing this, I've discovered ioctl(...) and
    the XENIX struct termio { } thing containing bit-controls
for input, output, control modes, line discipline, etc.
    Now, my question is, having set the local mode to ECHO,
    as I though I needed it, why I received a whole string
    of ^G's back -- screenfuls in fact. I now understand
    that ECHO should be off and is and the damn thing works,
    but now I'm just curious about what ECHo really is for.
    Comments?

2.  Do I spoil the surprise or spontenaity when I mail my
    questions like this? Should I save them for the meeting?
    Who, in fact, is getting this group?
    (Sorry, not "group", mailing list?)
