ABSTRACT:
According to the invention, a data transmission system is provided with apparatus which enables the problem determination requests from any ports of the multiplex modems (18) to be processed. When a link event is detected on a port or when a solicited command is received from a host network management facility computer (10), the network control program (NCP) in the communication controller (16) checks with the associated link configuration data as to whether the involved port is port A. If is not port A, NCP looks for port A which has the same NCP correlation number as the involved port. Then, the LPDA message can be sent through port A and can reach the remote corresponding port A if necessary.
