all.DB_mode When configured as cir for circular format, the
buffer works like a revolving file at all times.
The file is overwritten whenever the limit of
the buffer size (as configured in
all.data_buffering or s<n>.data_buffering) is
reached. As for linear format (lin), once the
limit of the kernel buffer size is reached (4k), a
flow control stop (RTS off or XOFF-depending
on how all.f low or s<n>.flow is set) is issued
automatically to the remote device so that it
will stop sending data to the serial port. Then,
when a session is established to the serial port,
the data in the buffer is shown to the user if
not empty (dont_show_DBmenu parameter
assumed to be 2), cleared, and a flow control
start (RTS on or XON) is issued to resume data
transmission. Once exiting the session, linear
data buffering resumes. If all.flow or
s<n>.flow is set to none, linear buffering is
not possible as there is no way to stop recep-
tion through the serial line. Default is cir. cir
all.DB_
timestamp Records the time stamp in the data buffering
file (1) or not (0). If it is configured as 1, the
software will accumulate input characters
until it receives a CR and LF from the serial
port or the accumulated data reaches 256
characters. Either way, the accumulated data
will be recorded in the data buffering file
along with the current time. The parameter
all.data_buffering has to be with a non-zero
value for this parameter to be meaningful. 0
