Hi,

 

Im trying to access a com port in appeon and it seems I  can use file open to access a serial port in Appeon, writing seems to work but reading I cant get to work? Is this a bug?

im using Appeon 2022 build 1900

I use this to open the port

 

FileOpen ( ls_com_temp+":", LineMode!, Write!, LockWrite!, Replace!)

 

Then when I use fileread  I get -1 return.
