| 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. |
