Notes:
1. Typicals at VCC = 5.0V.
2. GND = 0V.
3. The VDD voltage specification of 5.5V guarantees 5.0V ±0.5V with typicals at VCC–5.0V.
4. All outputs unloaded, I/O pins floating, inputs at rail.
5. CL1 = CL2 = 10 pF.
6. Same as note [4] except inputs at VCC.
7. The VLV voltage increases as the temperature decreases and will overlap lower VCC operating region.
8. Standard Mode (not Low EMI).
9. Auto Latch (Mask Option) selected.
10. For analog comparator, inputs when analog comparators are enabled.
11. Clock must be forced Low, when XTAL1 is clock-driven and XTAL2 is floating.
12. Excludes clock pins.
13. 0°C to 70°C (standard temperature).

Function and Description
The &HT command causes the modem to transmit tones for PTT testing. The test tone is
generated until a character is typed on the modem’s terminal. The country configuration
may disable this command. The modem returns an ERROR result if this command
is issued.
&HT0-9 DTMF tone for digit n where the command was &HTn.

The I command queries the modem for information that can be used to determine the
modem’s compatibility with other software and to ensure the modem is operating
properly.
I0 Displays product code. The modem reports its product code to the terminal.
The modem produces information text dependent upon its features and
capabilities.
I1 Displays ROM checksum. The modem reports the value of its ROM
checksum. The decimal number displayed is the eight bit sum (from 0 to
255) of all the bytes in ROM.
I2 Tests the ROM checksum. The modem checks its ROM to ensure it is
correct. The modem reports a result code indicating whether the ROM is
OK or in ERROR.
I3 Displays Software Versions. The modem reports the modem controller and
data pump software versions, and the modem controller software release
date, to the terminal.
I4 Displays Modem Identification. The modem reports a configured
identification message to the terminal.
