Thanks for the suggestion from both of you. I started out with an example from Bruce's website, Rentron, and I my thinking was the 254 was the qualifier. So, I thought by using a qualifier one tx work be matched to its own rx then if I built two neither would interfere or operate the other. The main question I was asking was Using SERIN2 baud being 4800bps the mode would be 16572. On the receiver I would use this:
SERIN2 serpin,16572,[wait(254),address1,address2,mydata1,mydata2,chk_su m]
Return

What I would like to know is using SERIN at 4800bps changing the above line for SEROUT it does not work. I see in the manual what is says for the calcultion etc for SEROUT2 but not for SEROUT. If I do this:
SEROUT serpin,16572,[wait(254),address1,address2,mydata1,mydata2,chk_su m]

Hmmm,....I hope this make sense, haven't had my coffee yet.

Thanks

BTW, Skimask, I see your point in using colons. Finding mistakes, typos etc is easier.
