The 2m licor connected to /dev/ttyS2 was removed today.

The licors at 16 and 43 meters were reconnected to ports
/dev/ttyS11 and /dev/ttyS17, but we're not sure at this point
which was connected to which port. Perhaps we can query the
serial numbers to determine which is where.

First test: 4 licors running at 10Hz, 19200 baud

(Outputs (BW 10) (RS232 (Freq 10.0)  (Baud 19200) (EOL "0A") (CO2Raw TRUE) (CO2D TRUE) (H2ORaw TRUE) (H2OD TRUE)
  (Temp  TRUE) (Pres TRUE) (DiagVal TRUE)))

This resulted in around 1200 spurious interrupts being reported in /var/log/isfs/kernel

Second test: 4 licors running at 5 Hz, 19200 baud

(Outputs (BW 5) (RS232 (Freq 5.0)  (Baud 19200) (EOL "0A") (CO2Raw TRUE) (CO2D TRUE) (H2ORaw TRUE) (H2OD TRUE) 
  (Temp  TRUE) (Pres TRUE) (DiagVal TRUE)))

This resulted in around 300 spurious interrupts/sec being reported in /var/log/isfs/kernel

Second test: 4 licors running at 5 Hz, 9600 baud

(Outputs (BW 5) (RS232 (Freq 5.0)  (Baud 9600) (EOL "0A") (CO2Raw TRUE) (CO2D TRUE) (H2ORaw TRUE) (H2OD TRUE) 
  (Temp  TRUE) (Pres TRUE) (DiagVal TRUE)))

This resulted in usually less than 50 spurious interrupts/sec being reported in /var/log/isfs/kernel. The kernel won't report more than
50/s, so this means there were very few reports of spurious interrupts showing up in /var/log/isfs/kernel.

Left it running at this setting.
