[RTTY] Dupes, and handling them

[Ed Muns]

Inferring you're the serial number sent to you by copying the serial number
from the subsequent QSO works most of the time, but not always.  A common
discrepancy comes from SO2R stations where serial numbers are both skipped
and duplicated, depending on the timing of QSOs between the two computers.
This is an unavoidable consequence of logging software not being clairvoyant
as to whether or not an ongoing QSO gets completed or not. 

On your experience with WriteLog X-ing out the prior QSO when you work a
dupe, I've never seen that happen.  The second QSO is marked with a D and
both QSOs go into the Cabrillo log.
