COM1
Purpose
Read or set the RS232 settings for the COM1 port.
Command
Query “COM1 baud, parity, data, stop”
“COM1?”
Classic “COM1=baud, parity, data, stop”
“COM1”
Arguments Baud: The baud rate. This may be ‘300’, ‘600’,’1200’,’2400’,’4800’, ‘9600’ or ‘19200’.
Parity: The data parity. This may be ‘O’ for odd, ‘E’ for even, or ‘N’ for none.
Data: The number of data bits. This may be ‘7’ or ‘8’.
Stop: The number of stop bits. This may be ‘1’ or ‘2’.
Defaults “COM1 2400,E,7,1”
Remarks The COM1 port is used to communicate to the RPM4. When the COM1 port configuration of the
RPM4 is changed, the program message reply (COM1 use only) is sent at the old COM1 settings,
but all subsequent communications are accomplished at the new COM1 settings.
A 250ms or longer delay after receiving the reply to this command will ensure that the RPM4 has
changed the COM port settings and is ready for communications at the new settings.

COM2
Purpose Read or set the RS232 settings for the COM2 port.
Command
Query
“COM2 baud,parity,data,stop”
“COM2?”
Classic “COM2= baud,parity,data,stop”
“COM2”
Arguments baud: The baud rate. This may be ‘300’, ‘600’,’1200’,’2400’,’4800’, ‘9600’ or ‘19200’.
parity: The data parity. This may be ‘O’ for odd, ‘E’ for even, or ‘N’ for none.
Data: The number of data bits. This may be ‘7’ or ‘8’.
stop: The number of stop bits. This may be ‘1’ or ‘2’.
Defaults “COM2 2400,E,7,1”
Remarks COM2 is generally used to allow the host computer to communicate through the RPM4 to an
additional device connected to COM2. This can be useful if the host computer does not have 2
serial ports available.
