It looks correct to me, it builds OK, and it seems to be working fine
with my SignaLinK USB.  I just logged into my city ARES BBS and checked
for mail - the connection stayed up and no errors were seen.  I think
your manual fixup was correct.

One thing I've noticed (with this new version and all versions of
0.10 I tried) - when I first start up the soundmodem, there appears
to be a long latency before it will send the first packet for
a connection - somewhere around 30 seconds.  This occurs even if the
channel is entirely idle.  However, if an inbound packet is received
successfully, the first outbound packet will be sent within a second
or so thereafter.

Feels to me as if the channel-inactivity timer isn't being initialized
successfully, but I haven't yet dug into the code to figure out why.
