Additional Result Code Subsets

NOTE: ARQ (Automatic Repeat Request) is used in this

manual to denote calls under error control.

&A

n

Enable/disable additional result code subsets. See the X

n

command earlier in this chapter.

&A0 ARQ result codes are disabled. This setting does not

affect an error control connection; the modem returns the
standard CONNECT messages if result codes are
enabled.

&A1 ARQ result codes are enabled, indicating that a

connection is under error control. Message 14 is
displayed if the modem is set to X0 and the connection is
at any rate from 1200 to 28.8K bps. The remaining results
indicate the connection rate and require a setting of X1 or
higher.
