You should neither send "BEL" or "07". You should send the number 7 as the ASCII character "x07" or directly as ch_to_send = 7;

All these control characters have numeric values below 32, i.e. below space in the ASCII table. Did you look at the link I posted? In some programs, these character values are corresponding to CTRL+ch, i.e. CTRL+A gives 1, CTRL+B gives 2, ..., CTRL+G gives 7, ...
