Handling Commands

The generation and processing of ASCII-formatted commands is central to the

interaction between various StreamNet devices and hence, the heart of a device driver

is how it receives and process ASCII commands. Figure 3-1 shows how the

StreamNet commands flow.

Figure 3-1 StreamNet command flow

As commands are received by the host StreamNet device, they are parsed to separate

out the various addressing fields, ASCII command, and command parameters. Once

the command is completely parsed, it is passed to the device driver for handling by the

appropriate Lua code. Refer to Figure 3-2 to see how commands are routed within the

driver.
