Just in case you don't have that volume: 1 Transmit Data 6 Receive Data 2 Data Terminal Ready 7 Data Set Ready 3 Request to Send 8 Clear to Send 4 Ring Indicate 9 Data Carrier 5 No Connection 10 Signal Ground Transmit Data, Data Terminal Ready and Request to Send are OUTPUT from the card, all others are input ( except ground which is neither ). +-------+ | 5 10 +-+ | 4 9 | | 3 8 | <----- View from rear of adapter showing polarization | 2 7 | | 1 6 +-+ +-------+ Good luck! -- Ed Clarke uunet!bywater!acheron!clarke
