 </codeblock> <section><title>Limitations</title> <p>P.I.P.S. applications and native Symbian applications can be launched from the Telnet client. However, to view the output of the program or interact with it, the standard input and output of the program must be accessible to the Telnet server. This is only possible with P.I.P.S. applications. With native applications you will only be able to retrieve the termination status; you will not be able to view the output or interact with the program. </p> <p>Permission will be denied for external programs that does not have the required capabilities to access directories that contain <filepath>/sys</filepath> and <filepath>/private</filepath> in their directory path. </p> <p> <b>Note:</b> For more information about the external commands supported by Zsh, see the <xref href="GUID-3F577531-9798-537F-8F8B-7CAB0257560C.dita">Zsh Command Syntax</xref> section. </p> </section> <section><title>See also</title> <p>For information on porting Standard C applications to Symbian platform see the <xref href="GUID-E2DE2C6F-E071-5E88-96F1-D71DDED84609.dita">P.I.P.S.
