Toshiba M10 Tests and Diagnostics Async Test, RS-232C direct cable is described in Appendix F

3 Tests and Diagnostics 3.9 Async Test

3.9Async Test

To execute the Async Test, select 7 from the DIAGNOSTIC TEST MENU, press Enter 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 01	Wraparound (board)
		NOTE: To execute this subtest an RS-232C wraparound connector
		(34M741621G01) must be connected to the RS-232C port. The RS-232C
		wraparound connector wiring diagram is described in Appendix F.
	This subtest checks the data send/receive function through the wraparound
	connector.
Subtest 02	Point to Point (send)
		NOTE: To execute this subtest, two machines must be connected with an
		RS-232C direct cable. One machine should be set as “send”(subtest 02)
		and the other set as “receive” (subtest 03). The wiring diagram for the
		RS-232C direct cable is described in Appendix F.
	This subtest sends 20h through 7Eh data to the receive side, then receives the
	sent data and compares it to the original data.
Subtest 03	Point to Point (receive)
	This subtest is used with subtest 02 described above. This subtest receives the
	data from the send side, then sends the received data.
Subtest 04	Interrupt Test
	This subtest checks the Interrupt Request Level of IRQ 4, 3 and 5 from the
	send side.
