How to use the RAW mode

[Phil1pp]

Can somebody please explain me how to use the RAW mode.
For example for reading outside temperature at 0x0101.
vclient -c "detail getTempA" tells me the command is
SEND 00 01 01 01 02;RECV 2 UT

But I couldn't figure out how to make the right raw command.
Nothing seems to be correct.
vclient -c raw, "SEND 00 01 01 01 02 RECV 2 END"
vclient -c raw, "SEND 00 01 01 01 02 END"
vclient -c raw, "SEND 41 05 00 01 01 01 02 0A END"
