[\fBTCTI OPTIONS\fR ]
This collection of options are used to configure the varous TCTI modules
available.
.TP
\fB\-T,\ \-\-tcti\fR
Select the TCTI used for communication with the next component down the TSS
stack.
In most configurations this will be the TPM but it could be a simulator or
proxy.
Supported TCTIs are
.if (\n[HAVE_TCTI_DEV]) or \fB\*(lqdevice\*(rq\fR
.if (\n[HAVE_TCTI_SOCK]) or \fB\*(lqsocket\*(rq\fR
\[char46]
