TEST 11:
RS--232-C (8274) TESTS
(h>
Test 11 verifies the RS-232-C port.
Note that to run this test,
you need to connect a loopback plug to Port B with the pin
connections listed in the special hardware requirements
subsection of Section 1.
The subtests for test 11 are
1.
Test 8274 control options.
2.
Data transfer test.
3.
Error condition test.
Subtest 1 programs the Intel 8274 chip and sends a small amount
of data through the RS-232-C port in loopback mode, which means
that what goes out Port B comes back in Port B.
This subtest
executes at all available speeds.
Subtest 2, also performed in
loopback mode, transfers large amounts of data at 19,200 baud.
Both subtests take interrupts.
Subtest 3 forces the various
error conditions, such as framing errors, that can occur via
loopback, and makes sure that the 8274 handles and detects errors
properly.
Errors
Test 11 can return the following errors:
Carrier not on.
D i d n ’t receive frame Error.
Corrupted data at specified byte (RX/TX data): x.
Data not transmitted after ~2 seconds for d.
Not all the data has been received, so far: x.
Unknown Port.
Bad RS232 port (d).
TX underrun on tty d.
