Arguments
A Print format 'A' - print data as Hex characters only.
B Print format 'B' - print data as both Hex and decimal characters with time stamp and port
number.
comm
r
Communication port (1 → 4; * = all ports) for receiving data.
comm
t
Communication port (1 → 4) for transmitting (printing) collected data.
Record Received Serial Data
Serves as a diagnostic tool that collects serial data from all comm ports and stores the received data in the
database RAM for analysis. This is especially useful for troubleshooting input interpreter problems. All but
4K of the remaining database RAM will be allocated for data collection. There must be at least 526 bytes
available (50 rows of data). It takes 10 bytes of storage for every character received. A 4K database can
hold 400 characters and a 256K database about 258,000 characters. To display data from only one port,
use multiple E%' commands to turn off each unwanted comm port
Data is displayed in rows starting with the oldest data first. The oldest data is written after the buffer is filled.
In this way the most recent bytes are retained.

This feature remains enabled, even when the Model 672/675 is powered down, until
explicitly disabled with the F%' command.
Collected serial data can be represented in two different print formats:
Format 'A' sends each character as the ASCII Hex value followed by a carriage return <CR> (see example -
Print Format 'A').
Format 'B' sends a time stamp, the ASCII Hex value, the ASCII decimal value, the ASCII character and the
comm port number followed by a carriage return <CR> (see example - Print Format 'B').

Passing a value of 256 will generate two control codes, <CR> and <LF> in that order.
