Motorola MVME2700 Series Installation And Use Manual page 83

In MVME761 I/O mode, the MVME2700 supplies SCSI terminator power
through a polyswitch (resettable fuse) located on the P2 adapter board.
The MVME2700 supplies a
LED-mezzanine/remote-reset connector, J1. When J1 is used as a remote
reset connector with the LED mezzanine removed, the
signal can be cabled to an external speaker. For the pin assignments of J1,

On the MVME2700 series VME module, the standard serial console port
COM1, accessible through the transition module, serves as the firmware

9600 baud is the power-up default for serial ports on MVME2700 boards.
After power-up you can reconfigure the baud rate if you wish, using the
PPCBug PF (Port Format) command via the command line interface.
Whatever the baud rate, some type of hardware handshaking — either
XON/OFF or via the RTS/CTS line — is desirable if the system supports
it.
