This code sample is named TTY. It demonstrates how to open, configure, and close, a serial communications port, and perform read/write operations for a TTY terminal emulation application.
Serial Communications Reference(Core OS Services)
Navigate to the solution file (*.sln), and double-click it. By default, the solution file is copied to the following folder:
C:\Program Files\Windows Mobile 6.5.3 DTK\Samples\PocketPC\CPP\win32\Tty
Microsoft Visual Studio launches and loads the solution.
Build the solution (Ctrl+Shift+B).
Deploy the solution (F5).
On the desktop, open a hyper-terminal, choose "Com1" or "Com2" and the baud rate (for example, 9600).If you connected the mobile device with the desktop through serial connection by using "com1", then choose "com2". Otherwise, choose "com1".
Connect the mobile device to the desktop through the chosen com port.
Launch the TTYapplication on the mobile device.
Type letters on the hyper-terminal and you'll see them appear in the TTYapplication window (and vice versa).
The mobile device must have an available COM port, and it should be connected through the COM port to the desktop.
Pocket PC SDK:Windows Mobile Professional SDK
Development Environment:Visual Studio 2005 or 2008.
