2. Press PageDown to enter “Advanced Port Settings” sub-dialog, there are some
noticeable fields for initialize the ports for advanced usage. You may skip this
step if you do not concern these features.
Feature
In “Port Feature Settings” sub-dialog, port feature [Terminal] is the only choice
if On Board Line Discipline is set to “Enable”. This is good for terminal
application users.
However, if On-Board Line Discipline is set to “Disable”, port feature could be
either [Transparent] or [Terminal]. In case of [Terminal], all the tty line
discipline jobs will be done on host which surely is a burden to the host. In case
of [Transparent], no time-consuming tty line discipline is applied for the port
except flow control, thus non-terminal applications such as data acquisition will
benefit from it, e.g. gain better throughput and performance. The
Intellio
C218
Turbo/PCI firmware will do Xon/Xoff flow control and H/W flow control if
ixon/ixany or ixoff are set via ioctl() system call. In this case, the Non-Modem
and Modem Baud Rate do not apply.
