Hayes Smartmodem 2400
Supported modes:
• Bell
• CCITT_OM
• CCITT_AM
Supported cables:
• Must use 92219Q modem cable.
Autodial modes: Hayes.
For HP Internal Use Only
This modem drives circuit 111 (Pin 23) instead of using it as an input. With either cable
(92219Q or A1703-63006), the Multifunction I/0 PCA drives this line and the modem drives
the same line.
Caution
I
This modem should not be used because all HP cables connect circuit 111 to
the modem. If this modem is connected, both the Multifunction I/0 PCA and
the modem drive circuit 111. This modem has been used in the past with the
CIO-based AP card and had the same problem.
Turn off all data compression modes.
The Hayes defaults for the modem lines must be changed to the following:
