My customer provided a: Perle OLAN Serial Device Server to connect RS232 over Ethernet. I can communicate to admin, and have setup a Com port over Ethernet.
DS5.3 does not seem to work. With remote connection, I do not see bytes being transferred. I set 9600,8,1,odd, I have tried various ports. Koyo 205/DL260
