RTS/CTS and XON/XOFF
Default: Disabled
Options: Disabled,
Enabled
These parameters are included for special circumstances, such as when
the host is communicating in a protocol that includes RTS/CTS and/or
XON/XOFF and needs to control data flow by using either or both methods.
See “Point-to-Point with RTS/CTS” and “Point-to-Point with XON/XOFF” on
page 3-10 for definitions.
Blocking Factor
Default: 1
Options: 1 to 127 records.
Allows the concentrator to buffer records (bar codes, counters, etc.) from
decoders and deliver them to the host in batches.
If, for example, the blocking factor is set to 5, the concentrator will buffer five
records in a row before releasing the batch of five to the host. (See also,
“<C>Send Partial Buffer to Host Command” on page 4-13 for related informa-
tion.)
Buffered data is transmitted to the host exactly as the concentrator receives
it (without separators and continuous if Preamble or Postamble have not
been defined).
The Blocking Factor buffer is limited in size to 248 characters (including the
address, preamble, and STX) or 127 records, whichever comes first.
Full Screens
Default: Enabled
Options: Enabled,

When enabled, Full Screens displays the full screen menus. When dis-
abled, the screen display shows only the single command line that appears
at the bottom of each menu.
