You need to specify the executable to debug before attempting to connect
to the remote machine:
lldb-mi --interpreter
-file-exec-and-symbols local/path/to/executable
-target-select remote host:port
Note that the file-exec-and-symbols command has some non-standard
extensions in LLDB-MI that are documented in
<https://github.com/llvm-mirror/lldb/blob/release_38/tools/lldb-mi/MIExtensions.txt>

The remote side seems not to receive any msg at all.
I am not sure that it is proper use for -target-select command.

Is there any MI command for connecting remote target ?
Using platform and target command with lldb, It works fine as follows:

twoflower@js1-desktop ~/local-hello> ls
a.out* hello.cpp

However, when I try the same thing with lldb-mi, I cannot connect to
remote target as follows:
------- host log --------
twoflower@js1-desktop ~/local-hello> lldb-mi-3.8.1
(gdb)
-target-select remote 10.113.62.251:1234 <http://10.113.62.251:1234>
^error,msg="Command 'target-select'. Current SBTarget is invalid"

I am not sure that it is proper use for -target-select command.
