(-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
