SHow
A device is a device name followed by a space and either a device number or an asterisk (*)
indicating all of that device. The valid devices are: REader, COnsole, GAte, TMs, FPr, SDI,
PUmp Pcu, and LOOP.
Additionally, a device may be a single word if it is one of the following:
ALL - Shows communication for all devices.
RBroad - Shows reader broadcast messages.
CBroad - Shows console broadcast messages.
ROUTer - Shows router activity.
Communication will continue to be displayed until ^C (control key -C) is typed.
Communication errors such as failure to respond or CRC errors are indicated. It must be noted
that since this display function is being handled at a relatively high level within the software,
partial responses from a device will appear to be a non-response.
