atmloop - get/set loopback mode of ATM interfaces
sets or shows the current loopback settings of an ATM interface, and allows
to query the loopback modes supported by the interface.
Some ATM cards can be configured to echo data back to the driver (local
loopback) or to the network (remote loopback). The echoing may be done at
several different levels:
bits sent to or received from the line interface
the analog signal
The levels supported by an interface can be queried with the -q option.
If invoked without options, atmloop displays the current loopback
set loopback mode. Followed by either -l or -r, both
options to set local and remote loopback at the same time (if supported by
the driver), or none of them to turn off any loopback.
- -l level
enable local loopback.
- -r level
enable remote loopback.
- -q level
query loopback levels supported by the interface.
print version number of atmloop on standard output and exit.
