I got this from sunsite.unc.edu:/pub/Linux/system/Admin/login.

We use this tool for statistics of our modem pools:

Example our command sac:

sac $* -T ttyD1 ttyD2 ttyD3 ttyD4 ttyD5 ttyD6 ttyD7 ttyD8 ttyD9 ttyD10 \
ttyD11 ttyD12 ttyD13 ttyD14 ttyD15 ttyD16 ttyS0 ttyS1

reports on all the usage on our digiboard pool ttyDx and our regular serial
ports.
