in reply to $SIG{ALRM} timeout and Win32::DDE::Client hangs?
See the POD:
Timeout (NEWVALUE)If NEWVALUE is present, set the timeout value (in milliseconds) used for DDE operations; return the old value.
The timeout value is initially set to $Win32::DDE::Client::Timeout when the object is constructed. $Win32::DDE::Client::Timeout is set to 1000 when the module is loaded.

In the absence of evidence, opinion is indistinguishable from prejudice.
