AT Commands and
S Registers
Table B-1 lists AT commands and S-registers supported by the
DataPort PCX modem. This table lists standard AT commands
and S-registers first (e.g., ATA and ATS0=0), followed by
extended AT commands: the ampersand (&) commands
(AT&C n ); the backslash (\) commands (AT \K n ); the percent (%)
commands (AT%E n ), and the plus (+) commands (AT+FCLASS).
Boldface type indicates factory default settings (see the &F
command).
See AT Command Guidelines in Chapter 5 for an explanation of
command entry and usage.

Description
ESCAPE SEQUENCE
Causes the DataPort PCX modem to exit Data mode
and enter online Command mode. The O command
returns you to Data mode.
The escape sequence must be preceded and
followed by a pause to distinguish it from data. (See
S12.) The value of the escape character can be
changed. (See S2.)
REPEAT LAST COMMAND
Repeats the previous command string entered. Do
not precede the A/ command with AT or follow it with
a carriage return.
