Does anyone know what causes a forum posting to lack a Reply button?
I am not able to reply to jcdammeyer's post today at 18:53.
If I were able to reply, I think he just needs to know that in objfpc mode methods require a prefixed @ to be called, which Delphi mode dispenses with.
i. e. what is required is
CommConnection.OnRxMsg := @SerialRxData;
