Serial data interface ports
The MGC has three serial data interface (SDI) ports. The ports can be
used locally for debugging, or they can be configured in the CS 1000E Call
Sever as system terminals. Only ports SDI 0 and SDI 1 can be used to
access the installation menu during initial configuration of the MGC. SDI 2
is not available during bootup. Due to a limitation of the three port cable
used, SDI 1 and SDI 2 do not use hardware flow control. Only SDI 0 has
full modem support.

TTY default settings
The default tty settings for the SDI ports are:
•
Baud rate: 9600.
•
Data bit length: 8.
•
Stop bit: 1.
•
Parity: none.
•
Flow control: none.
MGC serial port configuration change
If the serial ports are configured as SL1 terminals on the Call Server, the tty
default settings can be changed in LD 17. Any values configured in LD 17
are downloaded to the MGC and override default values. The downloaded
values persist over restarts and power outages. A system message is
output when the serial port baud rate is changed.
