4.4.4 PROGRAM MESSAGE DESCRIPTIONS
#
Purpose To allow the host PC to communicate with a device connected to the RPM4 COM2 port.
Classic “#xx”
Arguments xx: The string to send out of the RPM4 COM2 port. It must be less than
40 characters long.
Remarks The RPM4 COM2 port can be used to communicate to another RS232 device (such as
another RPM4). This allows the user to use a single COM port or IEEE-488 port on the
host computer to communicate with the RPM4 and another RS232 device. A carriage
return and a line feed (<CR><LF>) are added to the string.
After this program message is issued, the RPM4 will reply back every string received by
the RPM4 COM2 port that is terminated with a carriage return. Line feeds are discarded.
This will discontinue when the next query is sent to the RPM4.
There is no other reply from this program message. Prior to using this program message,
you must ensure that the RPM4 COM2 port is correctly set up to communicate with the
device on COM2. Refer to the “COM2=“ program message.
