What I use:

################################################## ######################
# dataport configuration
################################################## ######################

# configure RJ-45 port for FlarmView 57
$PFLAC,S,NMEAOUT1,61
$PFLAC,S,BAUD1,5

################################################## ######################

and set (on flarmview) data rate to 57,600 baud.

It's not really necessary to set the mode -- I asked Uros about this and he says it is non-critical (so flarmview probably issues it's own mode setting command on the dataport). What *is* critical, as you have discovered is that the datarate set in flarmcfg.txt and on flarmview (in settings on flarmview) match.

Have fun at Mifflin.
