AT Command Set

This Appendix contains a summary of AT commands used by the Stylistic ST4000 Tablet PC's modem.
There are several things to note about this set of commands:
• Commands should be entered as ASCII characters.
• Commands should begin with "AT", with a description of the character after the "AT".
• The commands are not case-sensitive; upper and lower case characters are treated the same.
• All commands should be followed by the "CR" character stored in "S3".
• Spaces are counted as characters.
• Command indication can be a selected letter or number message, or it can be no return message by designation.
• Data format is as follows:
Start bit Data bit
1 7
1 7
1 7
1 8
Note: Baud rate and data format are detected by the "AT" character.
