The SNAModemDeleteLink function should be called when a link is terminating to delete the resources associated with the link. The parameters passed in must correspond to those returned by a call to SNAModemAddLink.
void SNAModemDeleteLink(
MODEM_STATUS *pModemStatus
);
All resources in the link service associated with the modem status are deleted, and they must not be accessed by the IHV code after calling this function.
