Thanks Brandon!
I got my “help” from ~# sms
Usage: sms [ OPTIONS … ] { send | read | list | delete }
where  OPTIONS := {
         -d, –device <device> |
         -b, –baud-rate <rate> |
         -i, –interactive |
         -n, –non-interactive |
         –read-timeout <timeout> (default: 5000 milliseconds) |
         –verbose
       }
Should have tried ~# sms send 
Thanks Lonny, that worked!
