JSI Tip 0694 - The AT command parses differently on NT 3.51 vs NT 4.0.

(Windows NT 3.51)   AT hh:mm "CMD /C command and parameters"

(Windows NT 4.0  )   AT hh:mm CMD /C "command and parameters"

If you have a mixed version environment, you can force the NT 4.0 Service Pack 4 parser to to use the NT 3.51 parsing logic. Browse to:


Add Key name Parameters with a blank Class. Add Value name UseOldParsing to the Parameters key as a type REG_DWORD and set it to 1.
