Implement remote command support.

[f1rmb]

• Defaut port is 7643 (totally arbitrary)

• Using RemoteCommandDMRG, each network can be enabled or disabled (net1 .. net5, xlx): ~ $ RemoteCommandDMRG 7643 disable net2 M: 2021-03-20 11:48:40.494 Command sent: "disable net2" to port: 7643 M: 2021-03-20 11:48:40.545 OK

• Using RemoteCommandDMRG, a connection status can be retrieved: ~ $ RemoteCommandDMRG 7643 status M: 2021-03-20 11:49:13.513 Command sent: "status" to port: 7643 M: 2021-03-20 11:49:13.563 xlx:conn net1:conn net2:n/a net3:n/a net4:conn net5:n/a

Status are:

• n/a : not enabled in configuration, or currently disabled.
• disc : disconnected
• conn: connected

A returned string is expected from the socket connection, this is why I did not reuse the MMDVMHost's RemoteCommand (unless MMDVMHost RemoteControl is modified as well). EDIT: I raised a PR in MMDVMHost #688, to be able to use RemoteCommand on both softwares. So, just tell me, and I will drop the remote command tool in this PR.

The exit value can be used in scripting (also 1 if we didn't get any reply).

Some examples:

RemoteCommandDMRG 7643 status

Could you remove the remote control program part from this PR, and then I'll merge it.

Hi Jonathan.

Yes, no problem.

[f1rmb]
