Note: If LED 96, 24, or 12 are blinking 3 times a second then V.42 is enabled at that speed. If LED 96, 24, or 12 are blinking 1 time a second then data compression is enabled at that speed. If LED 96, 24, and 12 are on the modem is connected at 300bps. If LED 96 and 24 are on the modem is connected at 4800bps.
