libhamlib-utils binary package in Ubuntu Lunar s390x

 Most recent amateur radio transceivers allow external control of their
 functions through a computer interface. Unfortunately, control commands are
 not always consistent across a manufacturer's product line and each
 manufacturer's product line differs greatly from its competitors.
 .
 This library addresses that issue by providing a standardised programming
 interface that applications can talk to and translating that into the
 appropriate commands required by the radio in use.
 .
 This package provides command-line utilities to test the hamlib library and
 to control transceivers if you're short of anything more sophisticated:
 ampctl ampctld rigctl rigctlcom rigctld rigmem rigsmtr rigswr rotctl rotctld
