Formatting StreamDevice input

[Elmer Pensack <pensacke@gmail.com>]

I have a timer device that provides data over a RS232 serial interface. I’m using StreamDevice to grab the data and publish as PVs. The data contains several times. All the times come in as an ASCII string containing days, hours, minutes and seconds and I'm writing them to stringin PVs. However, the data does not contain any separators, so the data coming in looks something like 000024015 (i.e. 000 days, 02 hours, 40 minutes, 15 seconds). I know the ‘in’ command needs to match the incoming data exactly or else it is discarded, but is there a way to add formatting to the PV that is NOT in the data? All I want to do is add a ‘:’ separator between each part, so the PV value will be like 000:02:40:15. Any suggestions?

Thanks!
