The following OnBarcodeRead handler will split any barcode containing an ASCII
Linefeed (LF = 0x0A) character and terminated with an ASCII ENQ (ENQ = 0x05)
into two parts. The first part is put into the current IBM 5250 field and the second
part into the next field and then submitted to the IBM host. This technique is
used to login a user with a Code39 barcode in full-ASCII mode. All other
barcodes are passed on for normal input

if (lfIndex >= 0 )
{
var passwordStart = lfIndex + 1;
// Look for Full-ASCII Code 39 (ENQ = 0x05)
