The control character <ENQ> starts the test. It takes
approximately one second to complete the test.
6.3.32 TEP
Test EPROM. Test the EPROM. See Chapter 5.4.7
EPROM test (EP-t),  30.
S: TEP<CR>[<LF>]
R: <ACK><CR><LF>
S: <ENQ>
R: aaaa,bbbb<CR><LF>
The control character <ENQ> starts the test. It takes
approximately 5 seconds to complete the test.

Parameter Significance
Parameter Significance
a Test status
0 = Off
1 = On
CAUTION
EEPROM life.
A large number of write operations will reduce
the EEPROM life.
Do not repeat the EEPROM test more often
than necessary (e.g. in program loops).
Parameter Significance
aaaa Error status. See Chapter 6.3.9
ERR,  36.
