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>
