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><xref href="GUID-3100800B-B2F7-50EF-BD4C-3C345ECCB2A5.dita">The
Symbian build process</xref> 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>
