4.4.4 PROGRAM MESSAGE DESCRIPTIONS
#
Purpose To allow the host PC to communicate with a device connected to the PPCK+
COM2 port. This program message is obsolete. You should instead use the
“PASSTHRU” program message. This command is
not available when using the
enhanced command format. Instead, use the “PASSTHRU” command.
Classic “#xx”
Arguments xx: The string to send out of the COM2 port. It must be less than
40 characters long.
Remarks The PPCK+ COM2 port can be used to communicate to another RS232 device (such
as another PPCK+). This allows the user to use one COM port or IEEE-488 port on
the host computer to communicate with the PPCK+ and another device. A carriage
return and a line feed (
<CR><LF> ) are added to the string.
After this program message is issued, the PPCK+ will reply back the first string
received by the PPCK+ COM2 port that is terminated with a carriage return.
Line feeds are discarded. This will discontinue when the next program message is
sent to the PPCK+.
There is no other reply from this program message. Prior to using this program
message, you must ensure that the PPCK+ COM2 port is correctly set up to
communicate with the device on COM2. Refer to the “COM2=“ program message.

This example assumes that a second PPCK+’s COM1 port is connected to the
PPCK+ COM2 port. This example gets the version of the second PPCK+.
