Main features are:
For message transmission the Sent uses full implementation of the protocol, that is used for message exchange by software products like Microsoft WinPopup, Windows Messenger Service (net send), etc. Therefore the Sent is fully compatible with them.
Sent can only send messages and can't receive messages. To receive a message sent with Sent you can use one of the following software products: WinSent Messenger, WinSent Innocenti, Windows Messenger Service (net send), Microsoft Winpopup.
Sent works on all versions of Windows (7/Vista/XP/2000/NT/ME/98) including Windows Vista and Windows 7, where Messenger Service and net send command are missing.
