The CN2610 Device Control application allows you to choose between two different operation
modes: ASPP and RAW.
ASPP Mode—For applications that require setting up communication parameters or controlling
modem signals (DTR, RTS, Break, etc.), take advantage of Moxa’s ASPP lib to simplify your
programming tasks. ASPP takes care of the more basic protocol-level programming tasks, and
allows you to concentrate your energy on higher level, application-specific tasks.
RAW Mode—To control device data transmission directly, set CN2610 for TCP RAW mode.
Device control applications can use standard Linux/Unix Socket programming in Linux/Unix
environments, or WinSock programming in Windows environments. Standard socket
programming allows you to focus on pure data transmission, without needing to write code for
controlling serial ports or modem signals. ASPP can also be used to communicate with CN2610.
Linux/Unix socket programming and Windows WinSock programming both use IP as the
communication agent between hosts and devices. RAW mode is a good solution for handling pure
serial data communications applications that do not require setting up communication parameters
(baudrate, parity, etc.).
