ZCONFIG (3X)
Chapter 4 223
Response Data
data.termret.zaddr
This is the terminal ZLU which has been successfully created or modified. For
actions ZcDSC_CREATE_LTT_PTT and ZcDSC_CREATE_LTT_ON_PTT, it
is the newly created terminal ZLU with the correct checksum.
data.termret.error
This is the returned terminal configuration error:
0 - No error (successful)
< 0 - ZCOM error code
> 0 - zcntl() firmware status code
NOTES 1. For port configuration, it is possible to change only one byte of the
32-bit configuration word, by using an appropriate value in action. In
this case, the other bytes remain unaffected. Besides, actions 1-5
correspond to the functions supported by zport(3X), except that zport
(3X) does not allow remote port configuration.
2. The following is the zpconf_type data structure definition (from
<zcom/zcomsys.h>) used in port configuration. This structure allows
the cnfg data to be referenced by individual bit fields
(zpconf_type.bits.<field>), by individual configuration bytes
(zpconf_type.pconfig[<bytenum>]), or by its entire 32-bit value
(zpconf_type.pcval).
