O <07OSS> Sets Run mode (Operate)
P <07PSS> Sets Pressure mode
R <0ARdddSS> Sets Rate to ddd mL/hr
R <0BRdd.dSS> Sets Rate to dd.d mL/hr
S <07SSS> Sets Hold (Standby) mode

Command Parameters and Data
The characters following the fourth character (Command code) are
defined according to the command code only, except that they must
be printable ASCII characters and must be counted in the record
length.
There may be a minimum of zero and a maximum of 40 parameter
characters. Commands from the host will have no parameters unless
CI mode is active. Responses from the pump are as shown on the
table starting on on page 4.
The response for the volume infused, volume limit and rate in mL/hr
portion of the "D" command, and the CI commands is formatted as an
ASCII string representing a decimal value.
• The string represented by "a" returns the volume infused.
• The string represented by "b" returns the volume limit.
• The string represented by "c" returns the rate in ml per hour.
Field sizes
Pump versions 0.65 and below may return either of two formats
based on the values being returned:
aaa.abbb.bcc.cdddd or aaaabbbbcccdddd
If any of the values exceed the limits of the first format, then all
values are reported in the second format. Note that the least
significant digit in the first format is truncated when converted to the
second format.
Pump version 0.66 and 0.67 return a single format:
aaaa.abbbb.bccc.cdddd
