modules. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p> <b>Note:</b> Before you start to debug, check the Comms software configuration

since some configuration options may help with the task. For more information

see <xref href="GUID-0AC0CBBA-87AD-5F94-8F0D-D13654ABB631.dita">Software Behaviour

in a Debug Environment</xref>. Also, some software problems are caused by

an incorrect configuration. For more information on the configuration options

in Comms, see <xref href="GUID-B93D6BAE-B9B9-5118-92DF-5E566E5BE8EB.dita">Comms

Configuration</xref>. </p>

<p>Textual logging by the Symbian platform Comms software is

the primary means by which Comms software can be debugged. By default, this

textual logging is built into the debug Comms binary files and not into release

binary files. Mobile phone software contains the release versions of the binary

files. To debug the code you must use substituted debug binary files. These

debug binary files may also contain behavioural changes to make errors more

apparent and error tracing easier. These behaviour changes can also mask software

problems that are influenced by differences in timing. For more information

see <xref href="GUID-0EF25CCA-1E6B-5B62-8E77-9A670986C5EF.dita">Textual Logging</xref> and <xref href="GUID-ABE77283-EED8-5A33-B574-3B771EF11086.dita">How to Use ULogger with Comms</xref>. </p>

<p>For more information on debugging using On-target hardware see <xref href="GUID-84C20E6E-C5DF-5346-84A3-2D8C701303C8.dita">On-target

Debugging</xref>. </p>

<p>For more information on debugging specific Comms components see <xref href="GUID-935DF48C-F014-5E2A-8BE6-29B00C4FD31D.dita">Component-Specific

Debugging Help</xref>. </p>

<p>For information on the lower-level aspects of debugging such as the memory

map, process priorities and thread states see <xref href="GUID-26714A57-B6B4-5E81-B512-FB520718482B.dita">Debugging

information</xref>. </p>

<p>The Hooklogger application can be useful in tracking software defects such

as memory leaks, stray signals and non-trapped leaves. For more information

on Hooklogger in general and detecting memory leaks see <xref href="GUID-6A6A6648-6573-5EE4-A191-32B3C207305B.dita">Memory

leak detection</xref> and <xref href="GUID-0AC0CBBA-87AD-5F94-8F0D-D13654ABB631.dita#GUID-0AC0CBBA-87AD-5F94-8F0D-D13654ABB631/GUID-B8A8B315-8C46-551A-B8F6-29BD24F45435">Detecting
