and
follow the directions displayed on the screen. The Async test contains two subtests that test the
asynchronous communication functions. Move the highlight bar to the subtest you want to execute
and press
Enter.
Subtests require the following data format:
Method:
Asynchronous
Speed:
38400BPS (Subtests 06, 07)
Data:
8 bits and one parity bit (EVEN)
Data pattern: 20h to 7Eh
Subtest 06
FIR/SIR Point to Point (send)
NOTE:
To execute subtests 06 and 07, each computer must have access
to the other computer’s infrared port.
This subtest sends 20h through 7Eh data to the receive side, then receives the sent
data and compares it to the original data through the FIR/SIR port.
Subtest 07
FIR/SIR Point to Point (receive)
This subtest is used with subtest 06 described above. This subtest receives the data
from the send side, then sends the received data through the FIR/SIR port.
