Toshiba T1200 - 3.10 Async Test

3.10 ASYRC TEST
For subtest 01 to subtest OS, transmission is done as follows in
the communication.
Speed: 9600 BPS
Data: 8 bits + parity (EVEN)
1
stop bit
20H to 7EH
Subtest 01 Wrap around (channell) (Execution time: 1 second)
Bote: An RS232C wrap around connector must be connected to
channel 1 to execute this test. RS232C wrap around
connector wiring diagram described in part 3.22.
Performs a data send/receive test with the wrap
around connector for the channell.
Subtest 02 Wrap around (channel 2) (Execution time: 1 second)
Performs the same test as subtest 01 for the channel
2.
Subtest 03 Point to point (send) (Execution time: 1 second)
Bote: This test can be executed on condition that the both
send and receive sides are set in the same
condition, and also connected together by RS232C
direct cable (Wiring diagram described in part
3.22. ). Subtest 03 must be executed together with
subtest 04 and vice versa.
In this test, the data (20H to 7EH) are sent as one
block from one side to the other, and then returned
from the later one to the first side again.
This test is used to check wheter the returned data
are same as the original ones.
Subtest 04 Point to point (receive) (Execution time: 1 second)
This test is exactly the same as subtest 03 except
that the data flow is completely opposite.
