Appendix A. AT Commands and S-Registers

commands may be separated with spaces for readability. The maximum length for a command line is 40 characters. Each command line is executed by the Express XR/XRT upon receipt of a terminating character. The default terminating character is a carriage return (ASCII 013), but it can be changed by writing a different value to register S3. Before the terminating character is transmitted, the command line can be edited by using the backspace character (ASCII 008) to erase errors so the proper commands can be entered.

Using an AT Command

Type AT followed by the letter of the command and numeric value of the setting desired and then press Enter. The following command returns the software version of the unit:

ATI1

Using S-Registers

The configuration of the Express XR/XRT can be changed or reviewed with S-registers. See the section S-Register List in this chapter for a description of each S-register and its corresponding range of values.

Reading an S-Register

Type ATS followed by the number of the S-register to be read followed by a question mark and press Enter.

ATS0?

Reading an S-Register String

The Express XR/XRT uses S-register strings to store strings of digits for stored phone numbers, SPIDs, etc. Type ATSS fol- lowed by the number of the string S-register to be read followed by a question mark and press Enter.

ATSS80?
