I try man hm2_modbus, command not found as you see in attachment i have linuxcnc 2.9.4, i check in linuxcnc official site this is the last version, i dont know where is the problem 

Seems you would need 2.10 for it to work, see
buildbot.linuxcnc.org
but first try this
buildbot.linuxcnc.org/dists/buster/maste...fd6a133f8b_amd64.deb
download and install with gdebi

2.10 or 2.9 will work but you need a recent build.
(newer than 1 month ago)


 

Ther is no 2.10, where can i find it and i download the 2.9 now, and same problem help please

You cannot use the standard release as they are only updated about once a year.
For a binary update, you need to use the image built by the LinuxCNC buildbot:

buildbot.linuxcnc.org/

(The page is a bit old as 2.10 is the current LinuxCNC master version and 2.9
is the current release version)

 The other option is to build from source:
