With the correct cable you can connect them to a serial port (COM1..COM4) of a PC. 'Carrier detect' is the signal from a modem to the computer saying that it is detecting a data carrier signal from the modem on the other end of the telephone line. Please consider that most mobile phones contain a complete (fax-)modem. If you want to make a cable yourself, you can find the pinouts of the serial ports on the site of my friend Joakim Oegren: http://www.zettweb.com/semiconductors/hwb/menu_Connector.html http://www.zettweb.com/semiconductors/hwb/menu_Cable.html Greetings, Jaap -- Chip Directory -- http://www.chipdir.biz/ -- http://www.chipdir.info/ -- http://www.chipdir.net/ -- http://www.chipdir.nl/ -- http://www.chipdir.org/ -- And about 30 other mirror sites world-wide. -- -- To subscribe to a free 'chip issues, questions and answers' -- mailing list, send a message to [EMAIL PROTECTED] with -- in the body 'subscribe chipdir-L'.
