Connecting to the Service Port
The service port is an RS-232C Data Terminal Equipment (DTE) port,
configured at 19200 Baud, with 8 data bits, no parity and either hardware flow
control or Xon/Xoff flow control.
The 9-pin connector is compatible with serial ports on PCs. A PC may be used
to connect to the service port, using a 9-pin to 9-pin null modem cable.
For connection to another system, such as a UNIX workstation, a different
cable or an adapter may be required.
