I can confirm this bug.  Its root cause is the following stupid piece of shell code:

                     2)
                        brailleDevice=${parameter}
                        test "`expr "${brailleDevice}" : "/"`" -eq 0 && \
                            brailleDevice="/dev/${brailleDevice}"
                        test "`expr "${brailleDevice}" : "/dev/tts/"`" -eq 9 && \
                            brailleDevice="/dev/ttyS`expr substr ${brailleDevice} 10 2`"
                        ;;

The check for a leading slash should have checked if the string contains
any colons first.

This should get fixed ASAP.
