Setting the DSR Signal

The setultrap utility can be used to configure the DSR Always On option. This feature is used for systems where the wiring does not support the DSR signal but the Host application still requires that the DSR be active. When the DSR Always On option to set to "on," the driver will always report to the application that the DSR signal is "on". The syntax for the command is:

where:

-fspecifies the port the action should be taken on.

•/dev/ttyPS1 specifies port 1

•/dev/ttyPS1,/dev/ttyPS64 specifies port 1 through port 64 (ranges are separated by a comma with no space between them)
