7.1.2 Terminal Server Parameters
Parameters must be set to match those of the device port on the other end of the serial connection.
7.1.2.1 Device Settings
Device:
The Access Gateway interface to which the terminal server application will attach.
ttyS0 -
WAN port 0 (hdlc0 MUST be disabled in the L1-Device and Sync Server pages)
ttyS1
- Console/WAN port 1 (hdlc1 MUST be disabled)
- not available on the Access 1000.
ttyUSB0 -
USB serial adapter port 1
ttyUSB1 -
USB serial adapter port 2
...
ttyUSB7 -
USB serial adapter port 8
Baud Rate:
The rate in bits per second at which characters are transmitted. This field has a
range from 300 to 115200.
Data Bits:
The number of data bits per character. This field ranges from 5 to 8.
Stop Bits:
The minimum period of time between characters, in bit-time (so at 9600 baud and 1
stop bit, the delay between characters is at least 1/9600 seconds). If 1.5 is selected, then an
actual stop bit value of 2 will be used, as true 1.5 stop bits is not supported.
Parity:
An additional bit that can be used for error detection. If enabled, it is added to the end of
each character. Options are:
None No parity bit will be added.
Even A parity bit will be added so that the character has an even number of 1's.
Odd
A parity bit will be added so that the character has an odd number of 1's.
Flow Control:
The method of controlling data flow to the device. Options are:
None
No flow control method will be used.
XON/XOFF
XON/XOFF characters will be used to resume and suspend.
RTS/CTS
The status of the RTS and CTS signals will determine whether or not
data is transmitted.
DTR/CD Detection:
Select this box to have the Access Gateway react to changes on the
received DTR or CD modem control signal. The ttySn ports have a DCE interface, so the
received signal is DTR. The ttyUSBn ports are DTE, so the received signal is CD. If enabled,
TCP connections will only occur when this signal is raised.
Enabled:
Select this box to enable the terminal server application for the selected device.
7.1.2.2 Conversion Settings
Conversion Type:
Specify the method of passing data between the TCP socket and the
terminal device.
RAW: Data is passed transparently as received (byte stream).
LINE: Data from the terminal is passed transparently to the TCP socket. Data from TCP
is forwarded when a CR is received. LF following CR is stripped.
