Getting started with Phindows

Phindows is a connectivity tool that lets you use Microsoft Windows platforms to connect to and interact with graphical Photon applications running on a remote Neutrino computer.

This chapter describes how to get started using Phindows.

• Starting Phindows
  When you start Phindows, it displays a Connect dialog where you can specify the type of connection (TCP/IP or direct-connect serial), compression type, cache settings, and whether to connect to an existing Photon session. Various connection options are available, but the defaults usually work well.
• Configuring Phindows for TCP/IP use
  If you're using TCP/IP, there are several configuration issues that you need to check before you can use Phindows. The configuration should already be set correctly; if not, make the changes described below.
• Data-compression options
  Phindows uses data compression to compress the data that is sent from host computer to QNX target.
• Data-caching options
  Phindows makes very extensive use of data caching techniques to minimize the amount of data that needs to be transmiDatacachingtted from the host to the client machine. Thanks to this intensive data caching, Phindows is usable even on modem-link speeds as low as 9600 baud.
• Using Windows fonts
  In normal operation when connected to a remote host, phindows receives all text as bitmaps which have already been rendered by the Neutrino font manager. This mode of operation is best in most situations, but at very slow connection speeds you can improve performance by configuring Phindows to use local Windows fonts.
• Using snapshot or PgReadScreen()
  Phindows supports taking screenshots with the snapshot utility, or any other application that calls PgReadScreen().
