Chapter 7:Setting Parameters
Serial 1 And Console 2 Parameter Settings
Buffer
The value assigned to this parameter determines the size of the serial buffer used by
the application for both input and output. The buffer controls how much data the
application can send to or receive from a serial device.
Retries
Note: “Retries” is not available if “Nomad” or “Scan-See” is chosen as the
peripheral device.
This parameter determines the number of times the terminal attempts to transmit a
byte from the serial port. If the count specified in this parameter is exceeded, the
transmission fails. Keep in mind that the value assigned to this parameter must be
exceeded before data in the buffer is thrown away. To disable this parameter and
force the terminal to use “Retry Tmo”, this parameter should be set to ‘1’.
Retry Tmo
Note: “Retries” is not available if “Scan-See” is chosen as the peripheral
device.
This parameter sets the time in seconds that the terminal waits before transmissions
stop and data from the transmit buffer is discarded. Keep in mind that the value
assigned to this parameter must be exceeded before data in the buffer is thrown
away. A value of ‘0’ (zero) disables this parameter.
Input Tmo
Note: “Retries” is not available if “Scan-See” is chosen as the peripheral
device.
This parameter sets the time in tenths of a second that the terminal waits before
passing received data to the TESS or ANSI tasks.
