Subject: ao-dumplog: switch to 'e' command, display progress
X-Git-Tag: debian/0.5+77+gc57bd7f~3^2
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=5f26ad663b3f60dddc9d967206e365f45dc4acd1

ao-dumplog: switch to 'e' command, display progress

Using the 'e' command allows additional checking of the data,
including end-to-end checksums and detection of missing data.

Progress is displayed by showing the recorded flight state along with
a '.' for each eeprom block read.
