Working with the iPaqs

• It may be necessary to recalibrate your iPaq X configuration. Run:
  xcalibrate -cal -94 337 -70 255 0.
• To learn the name of the iPaq, type hostname. This should return mobile###.
• The iPaq networking runs in two different modes: adhoc and managed. Adhoc mode causes iPaqs to talk directly to each other, without the use of a base station; managed mode causes iPaqs to talk through the base station and allows them to access the Internet.
  • To switch to adhoc mode, type cardctl scheme adhoc.
  • To switch to managed mode, type cardctl scheme managed.
• To get files to the iPaq, set the iPaq into managed mode and scp the file to it. From a Linux machine, run scp (file) root@mobile###.dyn.cs.washington.edu and enter the root password when prompted.

To Talk to the iPaq using the Serial Connection

• In Windows, use hyperterminal.
• In Linux, use minicom.
• Set the configuration parameters to a speed of 1152000, parity 8N1, and no hardware flow control.
• In minicom, be sure to change the 'Modem and dialing parameters' to be empty; minicom should not send any string sequences to the iPaq.

Producing Sounds on iPAQ

• Use the system() function in <stdlib.h> to cat a dsp file to /dev/dsp. (Use the man pages for more info.)
• For example, system("cat endoftheworld > /dev/dsp") plays endoftheworld.
