Q: I am trying to open COM2 on the Graphics Client, but I get error 55 or the message that the port is unavailable. What's going on?
The default setting for older Graphics Client configurations is to disable COM2. You can enable COM2: by changing the following line in the ADSLOAD.REG file as follows:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Serial2]
"INT_Disable"=dword:0
