i have to do serial communication .. does anyone has an idea how to
manage it?
i have a multimeter who's generating data and is able to send it. i have
to write
a character "d" on serial line but it don't work. may i have to use
"sersup.llb" instead?
how do i manage there a string "d" ... it seems that there are only line
commands?

if anyone can help plz write me ... thx

Are you turning your program into an .exe file first? If so, make sure that
this line is in your labview.ini file:

serialDevices="COM1;COM2;COM3;COM4;COM5;COM6;COM7;COM8;
COM9;\\.\COM10;\\.\COM11;\\.\COM12;\\.\COM13;LPT1;LPT2;"

And, of course, include the driver for serail communications (which is
included by default)

Otherwise, I'm not sure. I haven't done much serial communications. Make
sure you have flow control set up the way you want (Xon/Xoff...etc.)

Hello,

Some MM take their RS232 levels from RTS and DTR lines. For example,
Micronta and Metex serial MM, you have to clear RTS and Set DTR lines for
the RS232 interface to operate.

Hope this helps.
