USING RAW PORTS
CONFIGURING A SERIAL PORT
USING RAW PORTS
In order to allow customers to implement simple ASCII protocols without having to ask Red
Lion to develop custom drivers, Crimson provides a new facility whereby the software’s
programming language can be used to directly control either serial ports or TCP/IP network
sockets. This functionality—known as raw port access—replaces the driver and functions
used to support the Roll-Your-Own Protocol facility within Edict-97. It also replaces the
General ASCII Frame protocol by providing a function to perform the parsing operations that
the driver previously implemented. Note that if you are not using custom ASCII protocols,
but are instead using the standard drivers provided with Crimson, you can skip this section.
CONFIGURING A SERIAL PORT
To use a serial port in raw mode, select the Raw Serial Port driver as shown…
The port’s Baud rate and other byte format parameters should be configured to indicate the
required communications settings, and the On Update property should be set to specify the
program that will be performing the communication. This program will be called continually
by the port’s communications task.
CONFIGURING A TCP/IP SOCKET
To use a TCP/IP socket in raw mode, select the Raw TCP/IP Passive driver as shown…
