|TALK||FFB4||Command a device on serial bus to TALK|
To use this routine 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. Then this data is transmitted as a command on the serial bus.
If a secondary address is required then the TKSA routine must be called immediately after this one.
