- Bay Technical Multiport Controllers Owner's Manual

 
To access the configuration mode of the multiport, connect a dumb
terminal (or a PC running a terminal emulation program) to the host
port: Port 5 of the 525H, Port 9 of the 528H and 529H, or Port 18 of
the 5218H. This port is factory configured at 9600 baud rate, 8 word
size, 1 stop bit, no parity, and XON/XOFF disabled.
If you do not have a dumb terminal or a terminal emulation program,
BayTech supplies a utility diskette which includes instructions to put
an IBM PC or compatible into a dumb terminal mode (see Section
3.2 ).
Send from this device the control character (factory default is
Control-T - 14 Hex) followed by ASCII capital C (43 Hex). The
multiport should respond with the main configuration menu as shown
in Section 6.1 . From this point on, configuration of the multiport will
be menu-driven. While in configuration mode, you may send
Control-S to stop scrolling and Control-Q to continue scrolling.

The multiport will respond to the receiving of the control character and
capital C with an identification block and a configuration menu of the
options available, similar to the following for the 528H:
