In upgrading a client from v14 to v16.2 (Mac based), I’ve noticed that RECEIVE
PACKET has become very slow, whilst RECEIVE BUFFER works fine. This is using
serial comms with a scanner (via Keyspan adaptor).
C_BLOB($rxBlob)
SET CHANNEL(101;Data bits 8+Parity none+Speed 19200+Stop bits one)
RECEIVE PACKET($rxBlob;Char(13))
// Delay of ~8 seconds between scan and getting here
Repeat
RECEIVE BUFFER($r)
$rx:=$rx+$r
Until (Position(Char(13);$rx)>0)
// Falls through to here on scan immediately
Thinking that it might be unicode, I’ve tried with blob and text, but no luck.
I can workaround by using RECEIVE BUFFER, but just wondering if anyone knows of
any other things I can try or if it is a bug?
