INTERRUPT TEST ON TTY#, ###CHARS, ##ERRS, ON TTY#,
#tlCHARS, ##ERRS
This message is di3played at the end of each
iteration of each cycle of the interrupt mode
test, and is analagou3 to the 3i'nilar display of
the polled mode test. Character and erro~ counts
are cumulative for all t23t cycles. Zero er-or
counts in both directions indicate a successf~l
test. The error count is the number of times that
the tran:5mitted character failed to :l1atch the
received character.
ERROR: CHARACTERS MATCH WITH MIS-MATCHEJ BAUD RATES!!
Indicates that 256 characters were succes3fully
transmitted despite differing baud rates in the
transmit and receivr~ PO('ts. T~1e bau,j ratc~ cl;Jcks
are not correctly set.
ERROR: DCD INTERRUPT NOT RE:EIVE0, TTY~, SfATJ3= ##
An error occurred in inter~upt-moJe ~e3ti1g af
modem signals. RTS and DTR were reset in the
transmit modem, which should have gene~at8j an
interrupt in the receive modem when nCD .and STS
are reset. If both polled mode and interrupt mode
modem
tests fail, the interconnecting cable should
be carefully checkedi however, if only one modern
test fails, the SIO LS probably at fault.
ERROR: DCD AND/OR CTS NOT CLEARED AFTER
CLEARED, TTY#, STATUS: #11
RTS/DTR
The
interrupt described in the previous er~or
occurred in the receive SIO modem; however, the
expected status of zero for both DCD a~j CTS did
not occur.
ERROR: DCD INTERRUPT NOT RECEIVED, TTY#, STATUS: UU
RTS was set on the transmit modem, which should
have caused an interrupt on the receive madem when
