Test Tn
The Test command is used to verify hardware and LED operation. The T0
command will turn-off the front panel Test LED. The T1 command will turn-on the
Test LED. The T2 command will cause the Digital232 to initiate a ROM/RAM test.
If the test is successful, all LEDs will flash for one-half second. If a test fails, the
Error LED will remain illuminated. Use the Status command to determine the cause
of the self test error.
Example:
@ reset the Digital232
T0 turn-off the front panel Test LED
T1 turn-on the Test LED
