ASCII Command Reference
Description of Commands
The c option in the COM command is A for MIRRORED BITS communications
Channel A, B for M
IRRORED BITS communications Channel B, and M for the
M
IRRORED BITS communications channels in general. If both MIRRORED BITS
communications channels are in use, then the M option does not function and
you must specify A or B.
COM c C and COM c R
The COM c C and COM c R commands clear/reset the communications
buffer data for the specified channel c. Options C and R are identical.
COM c L m n and COM c L date1 date2
Use COM c L to list the records in the communications buffer in a specified
manner. The relay returns the list of records in rows. You can specify a range
of buffer records in forward or reverse chronological order or in forward or
reverse date order. Date parameter entries depend on the setting DATE_F
format you chose in the relay Global settings. See Section 5: Settings for more
information.
The relay organizes the records in rows in a 256-entry buffer in newest to
oldest time order. The relay puts the newest record in the buffer and discards
the oldest record if the buffer is full.
Table 15.34 is a representative list of options for listing records in the
communications buffer.
