UltraPort 8i and UltraPort81 Express RTS/DTR option

The utility is used as follows:

The Perle UltraPort8i and Ultraport81 Express can only support either RTS or DTR. There is a utility included with this driver to configure which signal will be active. The configuration is stored in the modules.conf file.

set_io8_rts off

This is the default action. The driver will use the pin as "DTR" when the tty is in soft- ware handshake mode.

set_io8_rts on

If this option is used or hardware handshake is on, the pin will always be RTS.

Note

The perle serial module will have to be unloaded and reloaded for the
