<LI>Connect an external modem to your HPC using either a modem cable supplied by the HPC vendor or a standard null-modem cable and a 9-pin to 25-pin adapter connected to the optional HPC serial communications cable.
<LI>When using an external modem with your HPC, make sure the modem is turned on before configuring a dial-up connection. Your HPC will recognize the external modem only as a generic modem on COM 1 (unlike modem cards, the HPC does not recognize specific types of external modems).
<LI>If you are unable to dial out using an external modem, you may need to add special modem commands to the dial string -- you can add these on the <B>Call Options</B> tab when configuring the modem. For more information, refer to your modem documentation.
