Try this:
/term SCComm:1:"The reader name from /list-readers":protocol=1
Replace protocol with 0 for T=1. Keep in mind the name of the reader as it appears in your Device Manager will not necessarily be exactly the same as from /list-readers.
Example:
/term SCComm:1:"Identiv uTrust 2700 R Smart Card Reader 0":protocol=1
# Do a bunch of commands here
/close
