Example techniques of the present disclosure provide a first computing device comprising one or more processors and at least one module operable by the one or more processors to output, to a second computing device, a first set of HDLC protocol data units in accordance with a first format in which each of the first set of HDLC protocol data units includes a start-of-frame indicator, a length indicator, a data portion, and an end-of-frame indicator. The module may be further operable by the one or more processors to determine an inability of the second computing device to process at least one of the first set of HDLC protocol data units and output a second set of HDLC protocol data units in accordance with a second format in which each of the second set includes the data portion, a checksum portion, and the end-of-frame indicator and excludes the length indicator. |

1. A method comprising:
outputting, by a first computing device and to a second computing device, a first set of high-level data link control (HDLC) protocol data units in accordance with a first format in which each of the first set of HDLC protocol data units includes a start-of-frame indicator, a length indicator, a data portion, and an end-of-frame indicator; determining, by the first computing device, an inability of the second computing device to process at least one of the first set of HDLC protocol data units; and outputting, by the first computing device and in response to the determining, a second set of HDLC protocol data units in accordance with a second format in which each of the second set of HDLC protocol data units includes the data portion, a checksum portion, and the end-of-frame indicator and excludes the length indicator. |
