AMOSi:Serial Check

an example can be found on AMOSPro_Examples:Examples/H-4/Help_47.AMOS

Asks the device for a read-out of its current status. You can use it to check whether all the information you've transferred with a previous SERIAL SEND command has been correctly sent.

test=Serial Check(channel)

test = FALSE (0) -> the last serial command is still being executed.
= TRUE (-1) -> All done!
