5The command get_list_space was available on the RTC

3/RTC

4 to support their circular

queue mode and returned the distance between the input and output pointers. The RTC

doesn’t have a circular queue mode. The input pointer’s position can be queried via

get_input_pointer or get_list_pointer and the output pointer’s position can be queried

via get_status or get_out_pointer.
