I have to read barcodes with a Zebra reader and I just know that those barcodes start with **L-** and that Zebra adds **CR** to the end of the code - text length is not known. I've tried to use the _BarcodeScannerInput_ component in two ways:

- _prefix+suffix_ by setting _prefix_ to _L-_ and _suffix_ to _CR_ - the only way to set suffix to _CR_ was to add a button whose script sets _suffix_ to `\r` programmatically (tried also `\n` and any combination of `\r` and `\n`)
- _regex_ set to `L-([\w]+)$`

Neither of them worked for me. Any suggestion?  
Thanks in advance, regards
