GE MDS ORBIT MCR User Manual

MDS 05-6632A01, Rev. F MDS Orbit MCR/ECR Technical Manual 61
 Line Mode - Selection of the operation line mode of the serial port. Choices are:
- RS232 (DEFAULT)
- RS485 - 2 Wire
- RS485 - 4 Wire
 Baud Rate - The serial port baud rate in bps. Choices 1200, 2400, 4800, 9600, 19200, 38400, 57600,
115200 (DEFAULT), 230400.
 Byte Format - The data byte format in bits, parity and stop bits: Choices are:
- 7N1 - 7 char bits, no parity, 1 stop bit
- 7E1 - 7 char bits, even parity, 1 stop bit
- 7O1 - 7 char bits, odd parity, 1 stop bit
- 7N2 - 7 char bits, no parity, 2 stop bits
- 7E2 - 7 char bits, even parity, 2 stop bits
- 7O2 - 7 char bits, odd parity, 2 stop bits
- 8N1 - 8 char bits, no parity, 1 stop bit (DEFAULT)
- 8E1 - 8 char bits, even parity, 1 stop bit
- 8O1 - 8 char bits, odd parity, 1 stop bit
- 8N2 - 8 char bits, no parity, 2 stop bits
- 8E2 - 8 char bits, even parity, 2 stop bits
- 8O2 - 8 char bits, odd parity, 2 stop bits
 Hw Flow Control - Hardware flow control enable/disable (DEFAULT) using RTS/CTS lines
 Vmin - Receive Buffer Size - The minimum number of data bytes that will be buffered by the serial
port before handling of the data to be processed by the terminal server. (255 = DEFAULT).
 Vtime - Receive Inter-Byte Timeout - The amount of time between bytes of data on the serial port (in
multiples of 1 millisecond), that indicate the end of a serial message ready to be processed by the
terminal server. (100 = DEFAULT)
From the CLI, this sequence shows how to add console access to the COM1 and COM2 serial ports and
set the COM2 baud rate to 19200 bps:
% set services serial console serial-ports [COM1 COM2]
% set services serial ports COM2 baud-rate b19200

Terminal Server Settings
When configuring a serial port that will be used as a terminal server the VMIN and VTIME settings need
additional explanation. As described above VMIN is a number describing bytes that are received from the
interface, while VTIME is in 100
th
s of a second (100 milliseconds) intervals. They act together to control
serial data collection and transmission as described below:
 VMIN == 0; VTIME == 0: The terminal server will continuously read to see if a byte if data is
available and process each byte.
NOTE While this is a valid mode in most cases this causes a high processing load on the device that
may impact performance of other operations of the device.
 VMIN > 0; VTIME == 0: The terminal server waits to process data until at least VMIN bytes
of serial data are received.
