Re: Read data via RS323

Hello,
I need to read data via RS232 ,
Unfortunately mu code isn't working
Could anyone please point where i'm wrong?

This is part of my code :

iStatus = ComOpen(iPort)
iStatus = ComSetup(iPort,iBaudRate,iDataBits,iParity,iStopBits,iHandshake)
iStatus = ComReceive(iPort,sEOS,iTimeout,iMode,sStr,iByte)
Print "sStr is : " ; sStr
iStatus = ComClose(iPort)


Any help is welcomed !!!

Re: Read data via RS323

Hi,

After calls to the functions ComOpen, ComSetup, ComReceive you should check the iStatus variable to see which function is throwing the error.

Try this:
iStatus = ComOpen(iPort)
if iStatus=-1
    error -100, "ComOpen() failed"
endif

If you need further help, please post your code with the actual arguments instead of variables.

Regards,
Victor Brode
