SUMMARY
When using Works 4.0 on Microsoft Windows NT 3.51, the Dial This Number command on the Tools menu does not function because Windows NT 3.51 does not support the Telephony Application Programming Interface (TAPI).



MORE INFORMATION
When you use the Communications module in Works 4.0, Works will check the operating system. If the operating system is Windows 95, or Windows NT 4.0, Works will use TAPI. If the operating system is Windows NT 3.51, Works uses the Messaging Application Programming Interface (MAPI) communications method. Since Dial This Number in Works 4.0 only works with TAPI, the command does not function when running Windows NT 3.51.
