Xbeep (2018 and 2019) frequency #7
Description
Dear Finnbarr
I currently noticed that using Xbeep with the option -f gave no beep in the EFI-Shell:
Xbeep -f 0x1B9
and the error is: invalid or missing argument
However, if I use this command with a hex value that is NOT containing a letter A..F in the value (e.g. 0x300), the buzzer is beeping and the command works. :-)
Thing is that our buzzer is working best at 2730Hz resonant frequency, so 0x1B9 would be much preferred.
Probably, this happends due to a conversion of the ascii-hex-string. Could you fix this issue possibly?
Kind regards and thank you very much
