[6] Specification for function test
Outline
AT commands are used for the function test mode.
To enter the general mode, send the command “AT+XDIAG”.
Then the machine can accept all key test functions (see “All Key Test and Others” on page 2-70) and further commands from
the computer.

Logic of signals
1) Setting function (AT Command: AT+XDIAG)
Asynchronous (Consisting of 115200bps, data length 8, start 1, stop 1, and Parity None).
2) After shifting to Function Test
Incoming/Outgoing serial signals should be as follows.
ST D0 D1 D2 D3 D4 D5 D6 D7 PB SP
H
L
ST:
Start bit
D0-D7: Data bit
PB:
Parity bit
SP:
Stop bit
After AT+XDIAG
1. Transmission rate: 19,200bps
2. Synchro system
Asynchronous (Consisting of data length 8, start 1, stop 1, and Parity None)
Signal protocol
1. The personal computer requests a response from a mobile machine to establish communications.
2. When keys are pressed, appropriate key codes are transmitted serially.
3. ASCII Characters (only capitals in the case of alphabet) are used for incoming/outgoing serial signals. At the end, return
codes (0Dh, 0Ah) are added.
4. Once making a request, the personal computer cannot make another request until the mobile machine returns a certain
response. Time-out does not occur.
