(-f)Specifies name or range of names of the tty device on which the action should be taken. For example:

/dev/term/z1 -specifies port 1

/dev//term/z1,/dev/term/z64 -specifies ports 1 through 64 (ranges are separated by a comma)

(-l)Lists the protocol configuration for each serial port configured on the UltraPort SI. /dev/term/z1 232 slow term 1

/dev/term/z1 485fdx fast term auto 5 1

The first example shows a device named z1 configured for protocol mode EIA-232, slew rate limiting is set to slow, termination is on, and the baud rate multiplier is 1

The second example shows device named z1 configured for protocol mode EIA-485fdx, slew rate limiting is set to fast, termination is on, EIA-485 HDX TX Driver Control is set to auto with bit delay of 5 bits and the baud rate multiplier is 1
