Method and apparatus for handling on-line escape in multiple-modem connections

An apparatus for use in establishing a connection between terminals of a communication system, the connection comprising a serial arrangement of a plurality of data communication devices including two endpoint data communication devices, the apparatus comprising:

• at least one non-endpoint data communication device arranged within the serial arrangement of the plurality of data communication devices between the two endpoint data communication devices, wherein at least one of the endpoint data communication devices has a first type of escape to on-line command mode feature, and the non-endpoint data communication device is configured so as to have a second type of escape to on-line command mode feature different than the first type of escape to on-line command mode feature;
• wherein the at least one non-endpoint data communication device is configured to have the escape to on-line command mode feature of the second type by altering a register setting which is associated with the non-endpoint data communication device and utilized to implement the escape to on-line command mode feature;
• and
• wherein the register setting is changed from a default value associated with the escape to on-line command mode feature of the first type to a different value associated with the escape to on-line command mode feature of the second type.

A method for use in establishing a connection between terminals of a communication system, the connection comprising a serial arrangement of a plurality of data communication devices including two endpoint data communication devices, the method comprising the steps of:

• determining a first type of escape to on-line command mode feature associated with at least one of the endpoint data communication devices;
• and
• configuring at least one non-endpoint data communication device arranged within the serial arrangement of the plurality of data communication devices between the two endpoint data communication devices so as to have a second type of escape to on-line command mode feature different than the first type of escape to on-line command mode feature;
• wherein the at least one non-endpoint data communication device is configured to have the escape to on-line command mode feature of the second type by altering software which is associated with the non-endpoint data communication device and utilized to implement the escape to on-line command mode feature;
• and
• wherein the software is altered by forcing a detection routine of the escape to on-line command mode to return a specified value associated with non-detection of an escape sequence.
