Depending on your model and geographic region, your C-Series
handheld PC may include a built-in modem for making dial-up
connections over an analog telephone line (the kind used in most
homes and offices). You can use the modem to send and receive
e-mail, explore the Internet, send faxes, and connect to other
services. Additional software and services may be required in
order to perform some tasks.
See Appendix C, "Agency Regulatory Notices," for information
on the Compaq Series number for your handheld PC.
If your model does not have an internal modem, you can
use a PC Card modem or an external modem to perform modem
tasks. For information on using a PC Card with your handheld
PC, see Chapter 6, "Using PC Cards."
