I have recently tested my VT101 terminal with a loopback connector. It fails RS-232 loopback test, but it passes the 20mA current loopback test. After testing it a second time with the RS-232 test, the character that represents gibberish received appeared on the screen as I was typing the escape sequence, but it still failed the test. I do know that it transmits the data just fine because the floppy drive in a computer I connected it to activated when I typed the dir command. I am assuming that since the 20mA test passed, the problem is limited to the RS-232 portion. Could there be a loose/bad connection from the DB-25 port to the PCB? The terminal has worked perfectly in the past. The problem has only manifested itself recently.
