Cable Table Label -- Alert reader Phil Reese <preese@skat.usc.edu> wins the copy editing award for the week, noticing a serious typographical error in our chart listing the "standard" configuration for a Macintosh hardware handshaking cable. Somehow we switched the Macintosh pin numbers for handshaking in and out. Our apologies. The correct table is:
Mac function RS-232 function Mac pin DB-25 pin ------------ --------------- ------- --------- RxD (receive) Receive Data 5 3 TxD (transmit) Transmit Data 3 2 Ground Ground 4 & 8 7 HSKi CTS 2 5 HSKo RTS & DTR 1 4 & 20 GPi CD 7 8
