Can you use a different line? I have worked over 4000 systems remotely, and sometimes a particular line just will not pass data. The MICS and CICS have a timeout that will give the same error if you fail to connect in 3 attempts, you have to wait 20 minutes, but don't think that applies to 6x16 or 8x24, but not 100% sure of that.
Do you know what speed the RAD is set to? Also, is it a Fast RAD or one of the older ones?
