Hayes Smartmodem 2400 - HP 3000 9 8LX Series Installation And Configuration Manual

Hayes Smartmodem 2400
Supported modes:
• Bell
• CCITT_OM
• CCITT_AM
Supported cables:
• Must use 92219Q modem cable.
Auto-dial modes: Hayes.
This modem drives circuit 111 (Pin 23) instead of using it as an input. With either cable
(92219Q or AI703-63006), the Multifunction I/O PCA and the modem, drive the same line.
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/O PCA and
the modem drive circuit 111. This modem has been used in the past with the
CIa based AP card and had the same problem.
Caution
Turn off all data compression modes.
The Hayes defaults for the modem lines must be changed to the following:
