 SD is on the modem, the text is talking about a RS232 cable: "A standard
 RS-232C serial cable should suffice as long as all of the normal signals
 are wired:"
 
 I'd change SD for TD which is the correct term in our case (or TxD, but
 in this case RD must be changed for RxD).  TD is the data transmitted by
 the DTE (our computer) to the DCE (modem), RD is data to DTE from DCE.
 These descriptions come from a time where half duplex was common.
 s/Transmitted/Transmit/ etc. is not mandatory, in fact both versions are
 used.  So I'd keep the description but I'd s/SD/TD which is correct.
