WRITE Procedure or WRITEREAD Procedure
Bit 3 must be set to 1 and bit 4 to 0. If bit 3 and bit 4 are not set correctly,
the call is completed with file-system error 140 and the connection is not
established. OSI/TS responds with a DR-TPDU.
This buffer is organized similarly to the WRITEREAD completion buffer that
contained CR-TPDU negotiation-request parameters:
•
Following the MCW are any response values for connection-negotiation
parameters. See Figure 7-10 and Table 7-6 for details.
•
You can include up to 32 octets of user data. Figure 7-11 shows the
contents of the WRITE or WRITEREAD buffer.
OSI/TS uses the parameters you put into the buffer to build a CC-TPDU. It
checks the following values:
OSI/TS does not check any of the following parameters if you include them:
Security
Throughput
Residual error rate
Priority
Figure 7-11. WRITE or WRITEREAD Buffer: Accept Parameters
TSEL The TSELs must be identical to those in the CR-TPDU.
TPDU size The TPDU size must be equal to or smaller than that in
the CR-TPDU, and its value must be a power of 2 from
128 to 8192. (The parameter is specified as the exponent
in other words, a TPDU size of 128 is specified as 7.)
Version number The version number need not be included.
Additional
options
The additional options parameter must be exactly as
specified in the previous READ buffer, except that the
expedited-data bit can be set to 0 (expedited data is set to
OFF).
