Hi Ian,

I've also had good luck with using the built-in debug record for drvASCII. If it's not allready in your database just add a longout record named "debug", DTYP="Ascii SIO", and use the <debug> command prompt in your OUT field". If you don't use this already it shows the raw io serial stream as seem by drvAscii. Turn it on/off with a message button or similar to set the pv.

There's also various other debug levels you can set from the shell:
drvAsciiDebugLevel = 0
#drvAsciiDebugLevel = 64
#drvAsciiDebugLevel = 128


Hope that helps,
-Matt

Ian, I have several instances similar to this, where other text makes getting the number I want almost impossible. You might try <%5k%e;%*f;%*f;%*f;%*f>, if this doesn't work (most often because there is a space in the text that can't be matched), then read the info into a stringin record and forward link to a soft ai record that gets it's VAL from the stringin record.

Subject: drvAscii decode string



I'm trying to read the following into an ascii analogin record:

"=V913 1.13e-04;59;11;0;0"

  and to extract the 1.13e-04 or whatever.  Using <%5k%f> just times out
and so does <=V913%f>.  Using %e makes no difference.  If I read the
value into a stringin record, there is no problem apart from the fact
that it's a string.

Any suggestions?

TIA
