The z commands include a variety of functions. Some can be used to override the set up
jumpers inside the tablet. To void a z command, send the Reset command or repower the
tablet.
 Autobaud: Command overrides set up jumper AA. It changes the default baud rate
to Autobaud, described in Chapter 2. The character <SP> is an ASCII space.
After issuing z<SP>, ensure that the host port is set to the baud rate you want. Only
then can you issue the second <SP>. The tablet responds with an ASCII <ACK> at the
new baud rate.
 ASCII BCD report format: Command overrides set up jumper AB. It causes the tablet
to use the ASCII BCD report format.
 Binary report format: Command overrides set up jumper AB. It causes the tablet to
use the binary report format/
 8 data bits, no parity: Command overrides set up jumper AC. It programs the UART
to use an 8-bit frame: 8 data bits, odd parity. After the command is executed, the
tablet responds with an ASCII <ACK>.
 8 data bits, odd parity: Command overrides set up jumper AC. It programs the
UART to use a 9-bit frame: 8 data bits, odd parity. After the command is executed,
the tablet responds with an ASCII <ACK>.
 Increment confirmation: Command lets you confirm the current Increment Mode
value. The tablet transmits two ASCII hexadecimal characters followed by an ADCII
carriage return: XX<CR>.
 Firmware identification: Command sends a character string to the host that
identifies the tablet firmware version. The string is:
MM2 12x12 Tablet by Summagraphics Firmware Version x.xx<CR>
where x.xx is the firmware version and <CR> is an ASCII carriage return.
