* The description of extended syntax commands presented here is a simplified version of the information presented in ITU-T recom-
mendation V.250 (05/99). For further details, refer to Section 5.4 of recommendation V.250.
Table 2-1: E<value> Commands

Basic syntax commands use the following format:
<command>[<parameter>]
• •
Where <command> is a single character or a group of characters that represent

exceptions to these rules and they are noted for each command as needed. The
echo command in the previous example follows the basic commands syntax
structure.
Extended syntax commands
• No parameters: +<name>
• Single parameter: +<name>[=<parameter>]
• Multiple parameters: +<name>[=<parameter1>][,<parameterX>]
Where <name> is the name of the command and begins with an alphanumeric
character and <parameterX> is an optional decimal number. There are some
exceptions to these rules, and they are noted for each command as needed.
In addition to the standard command format, extended commands have a read
and test syntax. The host system uses the read syntax to pole the modem and
determine the current setting for the command parameters. Read syntax has the
following format:
Read syntax: +<name>?
The host system uses the test syntax to pole the modem and determine the
supported parameter values for the command. Test syntax has the following
format:
