I have tested this for hours...
PUBLIC SPortReceiveString AS STRING
SUB SPort_Read()
DIM s AS STRING
DIM ls AS INTEGER
ls = LOF(SPort)
'IF ls > 1 THEN DEC ls '<---always read 1 less than what LOF offers
READ # SPort, s, ls
PRINT s '<--help to debug
SPortReceiveString = SPortReceiveString & s 'accumulate input
'There is some testing of SPortReceiveString here
END
Comments:
Serial Port data received is in groups of about 120 bytes every 10 minutes.
Every READ event is a small bunch of characters received.
I have found out that it consistently happens that
the during the SPort_Read event of the second last bunch of chars,
there are more data being receive by the kernel or SPort control
but an event will not happen.
If I unREM the REMed line...
IF ls > 1 THEN DEC ls '<---always read 1 less than what LOF offers
then it works perfect every time.
An event will happen for the very past burst of serial data in.
