<section id="GUID-2925258F-CF25-46F7-B6B6-761615C7526B"><title>Build</title> <p>The source code for this example application can be found in

the directory: </p> <p> <filepath>examples\SerialComms\ServerClientSide\GlassTerm</filepath>  </p> <p>The source code may be in the directory in which you installed

the Symbian platform, or it may be in <filepath>src\common\developerlibrary\</filepath>. The source code includes the two project files needed for building

the example: <filepath>bld.inf</filepath> and the <filepath>.mmp</filepath> file. </p> <p>The Symbian build process describes how to build this

application, which results in an executable called <filepath>\epoc32\release\&lt;target&gt;\&lt;urel

or udeb&gt;\GLASSTERM.EXE</filepath>. </p> </section>

<section id="GUID-13E2D7B4-19BD-4EF5-BD11-96858ED96A9C"><title>Usage</title> <ol id="GUID-1DB8E591-3818-51E6-BDE0-89FFE8B6F96A">

<li id="GUID-A399AF4D-E821-5341-9645-B7F0FA42B76A"><p>Run the executable <filepath>GLASSTERM.EXE</filepath>. </p> <p>Executables for the emulator targets <filepath>wins</filepath> and <filepath>winscw</filepath> can be run on your

PC. Executables for ARM targets must be copied to your target platform

before being run. </p> </li>

<li id="GUID-BD9D8050-474C-5FD0-8485-08CED5D8AEEF"><p>Once running,

the glass teletype application performs two simple functions: </p> <ul>

<li id="GUID-3384ABA3-13A8-57F7-BE4F-7CC322BDA464"><p>Read any key

presses and send the characters to the serial port. </p> </li>

<li id="GUID-A44E9991-D87A-5E20-BC01-91454379BFF8"><p>Receive any

incoming characters from the serial port and display them on screen. </p> </li>

</ul> <p>It sends and receives at 19200 baud, 8 data bits, no parity,

1 stop bit. </p> </li>

</ol> <p>In order to see the application working, you must make a

suitable serial port connection. A simple way is to connect a PC and

a Symbian device, and run the application on both machines simultaneously.

(Before doing this, make sure to close down any other applications

using the serial port on the PC, and set the device's <systemoutput>Link To Desktop</systemoutput> option to <systemoutput>Off</systemoutput>). Characters typed on one machine are then echoed to the application

on the other. </p> </section>
