Re: [Quickfixj-users] Reset Sequnces Design

[Liubov E. <liu...@gm...>]

Hi,

One more question about *ResetSeqNumFlag* behavior.
Does *ResetOnXXX=Y *options enforce to set *ResetSeqNumFlag* in the logon
message (both cases, acceptor and initiator) or not (just provide in/out
sequences reset to 1)?
