Description
The Host requests the Equipment to change the Access Mode for the specified Load Ports. ACCESSMODE specifies the desired
Access Mode. PTN specifies a desired Load Port Number.

Exception
If n = 0, then the command applies to all Load Ports on the equipment. If any specified port is already in the specified Access
Mode, then the Equipment shall accept the command, and toggle all loadports to specified mode. If the Equipment is unable to
change one or more of specified Port(s) to the specified Access Mode, then the Equipment shall accept the command (with
appropriate response acknowledgement), and shall change only the Access Mode of those Port(s) allowed by the equipment,
supplying the host with an indication that not all ports were successfully changed.

S3,F29 Carrier Tag Read Request S,H->E, reply
Description
The host requests the equipment to read data from the carrier tag of a carrier. The carrier must be identified either by its location
identifier or its carrier identifier, or both. DATASEG may be used to indicate a specific section of data to be read.
DATALENGTH is used to limit the amount of data for that section.

Exception
Either LOCID and CARRIERSPEC can omitted (zero length item), but not both. If DATASEG and DATALENGTH are both
omitted (are zero length items) then all data is requested. If DATALENGTH only is omitted, then all data within the indicated
section is requested.

S3,F31 Carrier Tag Write Data Request (CTWDR) S,H->E, reply
Description
The host requests the equipment to write data to a carrier tag. The carrier must be indicated either by its location identifier or its
carrier identifier, or both. DATASEG may be used to indicate a specific section of data to be written or overwritten.
DATALENGTH may be used to indicate the length of the data to be written.
Structure

5. <DATA>
Exception
Either LOCID and CARRIERSPEC can be omitted (zero length item), but not both. If DATASEG and DATALENGTH are
both omitted (are zero length items) then all data is to be overwritten. If only DATALENGTH is omitted, then all data within
the indicated section is to be written.
