LISTEN FFB1Command a device on serial bus to LISTEN

This routine will command a device on the serial bus to receive data. The accumulator must first be loaded with a device number between 0 and 31. When called, this routine then ORs bit by bit to convert this device number to a talk address. The specified device will then go into listen mode, and be ready to accept information.
