With the introduction of the Ti-Connect software, Texas Instruments have incorporated a new command which returns some version informations.

Getting OS & BIOS version

The protocol for silently receiving the clock is shown below:

Step	Direction			Packet
1				VER
2				ACK
3				CTS
4				ACK
5				DATA
6				ACK

Example (PC requesting version):

PC:	08 2D 00 00	Request informations
TI:	98 56 00 00	Acknowledgement of REQ
PC:	08 09 00 00	Clear to send variable
TI:	98 56 00 00	Acknowledgement of CTS
	88 15 0E 00 02 09 01 07 00 01 09 01 00 00 00 00 00 03 21 00	Variable data: 14 bytes (OS: 2.09, BIOS: 1.07)
PC:	08 56 00 00	Acknowledgement of variable data

The variable data has the following format (pure binary and/or BCD):

Offset	Length	Description
0	2 bytes	OS version like 02 09 for 2.09
4	2 bytes	BIOS version like 01 07 for 1.07
6	1 byte	Battery level: 00 = good, 01 = low
7	1 byte	Hardware Revision ? (0 = HW1, 1 = HW2, 2 = HW3)
8	2 bytes	Language ID ( 0x0901 for English)
10	2 bytes	Always 00 00
12	2 bytes	Always 00 00
14	2 bytes	Hardware ID (1 = 92+, 3 = 89, 8 = V200, 9 = Titanium); see TIGCC doc.
