Internal Modem
The Power Macintosh G3 computer includes an option for an
internal modem. The modem interface to the main logic
board is a 70-pin connector. The external I/O connector for
the modem is an RJ-11 connector located on the rear of the
computer. The modem has the following features:
• modem bit rates up to 56 Kbps (supports K56flex and
V.90 modem standards)
• fax modem bit rates up to 14.4 Kbps
The modem appears to the system as a serial port that
responds to the typical AT commands. The modem provides
a sound output for monitoring the progress of the modem
connection.
