M SERIES DAC
BASE UNIT AND MODULE OPERATION

buffer utilization and minimize network data traffic, data buffers are
held for up to 100 milliseconds or until full before being sent to the
receiving workstation. This allows for packing of data and prevents
transmission of an excessive number of packets with small amounts
of data. For most applications, this aspect of operation poses no
problem. But for some applications, the transmission delay may be
undesirable. In the case of 4 port serial modules configured to
operate in the immediate message mode (see DAC reference for
V74/75 programming), the V72 may be configured to send all
messages immediately upon receipt when this option is enabled.
Default is "disabled".
4) "CRT"----Carriage Return Translation. Carriage return translation
reconciles discrepancies between the TELNET end of line
convention and other types. TELNET applications will typically
place either a null (0x0) or line feed (0xa) after a carriage return. This
may cause unpredictable operation if terminal devices
connected to the DAC are expecting only a carriage return. By
enabling this option, the V72 will strip off any null or line feed which
follows a carriage return prior to sending the data on to its
destination. Default is "disabled".
5) “MENU”----Menu Mode of Operation. This option allows the user
to enable or disable the “MENU”/attention character mode of
operation. If the “MENU” mode of operation is disabled the V72
will be in the ASCII string mode. The default setting for the
V72 is the “MENU” mode of operation.
6) “BrkLen”----Programmable Break. Users may configure the
V72/V72TP for a break length of 25 - 6.375 milliseconds
(.025 - 6.375 seconds) in 25 millisecond increments. When a user,
running a Telnet session with the V72/V72TP and connected to a
serial port on a V74/V75, sends a Telnet break command (0xF4) to
the V72/V72TP, the serial port will send a break signal of the
programmed duration. The default setting for the Programmable
Break on the V72/V72TP is 350 milliseconds.
7) “Hst Cfg”----Host Configuration. Users may configure a
V72/V72TP to allow it to be configured through other host modules,
rather than just through the serial port. The default setting for “Hst
Cfg” (Host Configuration) is disabled.
