Hailing Handhelds
Non-Windows CE-powered handhelds still have a way to go and can't be used for much more than messaging and basic remote access. Windows CE personal digital assistants, naturally, work much better in this regard.
Palm has done a bang-up job of providing software to make sure your Palm synchronizes with Outlook, Notes and any other popular Windows-based messaging platforms. Pretty much any other kind of access is out of the question though, in large part because Palm doesn’t provide anything like a network file sharing client, network printing and so on. However, Palm is a workable platform for remote control, making Terminal Services a network resource that’s potentially open to Palm users. For that matter, many other handheld computers that aren’t powered by Windows CE could potentially use Terminal Services if only an RDP client was available.
I can hear you now: “You’re kidding—Terminal Services on a postcard-sized screen?” I’m not suggesting that it’s ideal, but it’s one way to make specially designed applications available and provide emergency administrative access to remote servers. For better or for worse, Microsoft—and most independent developers, as near as I can tell—agree. As a result, there’s no decent RDP client for the Palm platform.
But let’s forget RDP for a moment. There’s a VNC client available for
Palms, www.btinternet.com/~harakan/Palm
VNC/. As shown in the figure, the application even
provides a menu to send Windows-specific keystrokes, such as the all-important
Ctrl-Alt-Del sequence, to the VNC host. Of course, running VNC on a server
opens a number of security concerns. Learn more about VNC for Windows
and other platforms at www.uk.research.att.com/vnc.
Citrix, makers of MetaFrame XP, has the cross-platform thing in the bag,
so it’s curious that the company doesn’t offer a Palm ICA client. It does,
however, offer a Symbian client that runs on certain Nokia phones; and
its Linux ICA client runs on Linux-based handhelds such as the Sharp Zaurus
series.
Talk to Your Phone
What other type of handheld interoperability might you need? If e-mail
access from a cell phone comes to mind, you’re in luck. Some phones offer
access to POP3 mailboxes, allowing them to access Exchange and other server-based
e-mail. Most so-called “connected” phones include a Wireless Application
Protocol (WAP) browser, which provides access to specially formatted Web
sites. Microsoft’s own Mobile Information Server (MIS) provides Outlook
Mobile Access (OMA), which is essentially a WAP version of OWA. OMA works
with Exchange 5.5 and later and provides mobile phone users with access
to e-mail and contacts.
Other handheld interoperability is pretty much limited to what the handheld’s
manufacturer provides. Many mobile phones, for example, can synchronize
with Outlook through the use of a special cable and software provided
by the phone manufacturer. Other handhelds, like the Sharp Zaurus series,
also provide proprietary synchronization software with Outlook and other
PIM software.

Communing With CE Devices
Microsoft Pocket PCs, like the popular HP iPaq series, benefit from a
scaled-down version of Windows built right in. That means you get a number
of fantastic interoperability features right out of the box. For example,
Pocket PCs come with miniature versions of Word, Excel, PowerPoint and
Outlook. Their built-in ActiveSync software makes synchronizing your desktop
data easy: Just install ActiveSync on your desktop, plug your Pocket PC
into its docking cradle, and you’re done.
MIS even includes Server Active-Sync, which lets wireless Pocket PCs synchronize Outlook data directly with an Exchange server. Server ActiveSync is scheduled to be included in the next version of Exchange Server, code-named Titanium.
