The Computer Interface Message Distribution (CIMD)
protocol was introduced by Nokia. The Nokia SMS Center includes a
CIMD2 interface that transfers messages between applications and the Nokia
Short Message Service Center (SMSC).
CIMD2 is version 2 of the
Computer Interface to Message Distribution protocol. The CIMD2 interface is
suitable for client applications that send and retrieve messages over TCP/IP
sockets, such as Ozeki NG - SMS Gateway.
