I have a Hollis DG03 (uses oceanic_atom2 protocol).  The computer
reports its serial number as 000481, and firmware revision 1b.

stderr when downloading dives (no new dives) from subsurface on linux:
loaded the Generic plugin
libdc devinfo serial nr converted to 0000-0481
[0.132175] ERROR: Unexpected answer start byte(s). [in
oceanic_atom2.c:401 (oceanic_atom2_send)]

[rick at localhost subsurface]$ subsurface --version
Subsurface v4.2.90-38-gfc7f0c621501, built with libdivecomputer
v0.5.0-devel (b2bc231cb472cb5eb409abb9ce493130b00e9526)

I read this as it's reporting the serial number correctly but doesn't
know anything about firmware.
