When receiving on the UGC-136BX, I am seeing an interruption (CR) if the receive line is idle (at a mark) for more than 9 seconds. The next received character after the idle is printed but preceded by two LF characters and "A.P." (The auto-print is set).
When receiving the text, the "rec unprt" light is on.
This is slightly annoying 8-)
e.g.
A.P.
THE QUICK BROWN FOX
A.P.
THE QUICK BROWN FOX
The manual (p3-5) says,
"If a message is received without an SOM or an unmatched SOM, the message is determined to be
unformatted and assigned an MPN equal to 0.
...
If the
AUTOPRINT/NORM/MASTER CLEAR switch is in
the AUTOPRINT position, the received
messages are printed and then automatically deleted from memory.
"Is anyone else seeing this behavior?
Test....
1. Send characters to the UGC-136BX
2. Observe the text printed and the "rec unprt" illuminates
3. mark continuously for 10 seconds - observe the "rec unprt" light extinguish and the carriage returns.
4. Send more text - observe two LF chars, "A.P.", CR + LF printed and then the text.
