RS-232C interface and computer connections
Computer
A player accepts commands at any time. It is unnecessary
to connect control lines other than TxD and RxD when joining
to a computer with a standard RS-232C port.
Some computers fail unless the CTS input is hard-wired.
In this case, the DTR output is used. If the DTR is active, a
"+" electric potential is output.
