Root adb shows rca as offline, sideload shows host

[androidcustom18]

I found an adb program that atleast shows that something is connected, when the tablet is on adb says the device is offline with numbers, and when i try to push from here all i get are errors, then when i get into recovery adb sideload, it shows up with different numbers and it says host, but i keep getting the syntax wrong. Any input would be appreciated.
