C-12 Appendix C
Configuring the Remote Support Modem
Configuring Individual Modems
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 A1703-63006) the same line is driven by the Console/LAN card and the modem.
CAUTION This modem should not be used because all HP cables connect circuit
111 to the modem. If this modem is connected, circuit 111 will be driven
by both the Console/LAN card and the modem. In the past, this modem
was used with the CIO-based AP card and encountered the same
problem.
Turn off all data compression modes.
Settings
The Hayes defaults for the modem lines must be changed to the following:
