Loading a K0055 (BCD) into word +0007 will request that the DCM recognizes (looks for) new
or desired port communication parameters that are written to the DCM port configuration
registers. If the requested changes are valid, a 00AA (hex) will then be written to word +0007.
If the desired or new communications are invalid or out of range, an error code 00E* (Hex) will
be written to word +0007. The last digits indicate the address that has an error. For example,
error code 00E2 means that word +0002 has an error.
Use word +0024 to set Port 1 and Port 2:
