No, the list of switches is from vt_openterm... I figured I'd try it from my Mac first to see what the performance was like (obviously a POS app would generally be on a LAN, rather than over home broadband):

andrew@willow:~ $ ssh -X viewtouch@demo.viewtouch.com /home/viewtouch/bin/openterm
Password:
Usage: vt_openterm [OPTIONS] <display address>
OPTIONS:
-c Close the terminal instead of opening it
-C Clone an already open terminal
-d <number> Number of drawers attached to terminal
-D Enable debug mode
-h Show this help screen
-n <name> Terminal name
-p <port> Remote port to connect to
-P <printer> Printer host
-r <remote> Remote host to connect to
-t <type> 'kitchen' or 'normal'
-T <printer type> 'epson', 'star', 'ithaca', or 'text'

...and then it just sits there.

HTH,

Andrew
