CAPI 2.0 Messages

These are common CAPI message and error codes listed by workgroup and expanded by V.110, 1.TR.6 and manufacturer-developed messages. All messages are shown as four hexadecimal digits (i.e., each ranging from '0' to 'F'). If a message starts with "33" (i.e., "33xx"), it usually hints at an installation problem with your ISDN board or telephone system. Error messages of the "34xx" variety are caused by a remote party or the ISDN net itself. In case no modem answer is supplied below, the modem returns a NO CARRIER signal.
