The escape character is determined by the value stored in S-register S2, and it is typically a ‘+’ character. The following is an example of the TIES Escape Sequence:

Format: <char1><char2><char3><AT command><contents of S3>

char1 = char2 = char3 = escape character (S2)

Example:

DTE: +++ AT<CR>

DCE: OK

Note: TIES requires that the three-character escape sequence be contiguous and not repeated. The character immediately preceding the first character of the three-character sequence cannot be the same as the escape character. Therefore, “+++ AT <CR>” is valid, but “++++ AT <CR>” is not.

Command Default Description

Repeat Last Command: This command re-executes the last AT command string stored in the command buffer. A/ is the only command not preceded by AT and end- ed by a carriage return.

A/ none

Sending any character (such as a carriage return) after A/ and before a modem re- sponse is sent to the DTE causes the modem to abort the remainder of the com- mand string in the modem internal command buffer.

A none

Answer Command: This command causes the modem to immediately go off-hook and initiate an answer mode handshake without waiting for an in- coming ring signal. This command is useful for manually answering a call or establishing a back-to-back connection with an originate-mode modem.
