Serin serout problem

[rhino]

If you're not using a Qualifier, I think you need to use Serin2. Maybe you can use it without the qualifier... I don't know.

SERIN Pin,Mode,{Timeout,Label,}{[Qual...],}{Item...}
‘ Wait until the character
serially on Pin1 and put
SERIN 1,N2400,[“A”],B0

....The list of data items to be received may be preceded by one or more
qualifiers enclosed within brackets. SERIN must receive these bytes in
exact order before receiving the data items.

SERIN2 DataPin{\FlowPin},Mode,{ParityLabel,}{Timeout,Labe l,}[Item...]
‘ Wait until the character “A” is received
serially on Pin1 and put next character into B0
SERIN2 1,16780,[WAIT(“A”),B0]

Either way, I'd try to send a qualifier down. Either the Serin format or as noted in the manual with Serin2.
