I use a regular serial cable with a null modem adapter. The following is from one of our quick reference guides:
Resetting Partner Mail or Merlin Mail To Factory Defaults
1. Connect a null modem and a serial cable from the com port of your PC to com port one of the voicemail.
2. Start Hyperterminal on your PC and set the program for 1200 baud, 8 data bits, 1 stop bit, no parity.
3. Power on the voicemail and you will be able to watch the boot up sequence.
4. When boot up is finished you will get a password prompt. The password is br00k. Note that the password is lowercase and the 0’s are zeroes.
5. You will now see a menu. Press B to perform the shutdown procedure.
6. When the voicemail is finished shutting down all the port lites will extinguish and the menu will return. Press the escape key to go to a C: prompt.
7. At the C: prompt type init and then press the Enter key.
8. You will see a warning message that all data will be lost. Press Y and the Enter key to continue with resetting of the voicemail.
9. Allow about 10 minutes for the voicemail to reset. You should be back at the main menu when the reset is complete.
10. Press A to restart the voicemail. Allow about 5 minutes for the restart to complete. All the green port lites will be lit when ready for operation.
