Serial
My serial device does not function.
The extender supports serial devices at data rates not exceeding 19.2K
Baud (although 38.4K operation might be possible with certain
equipment).
Check the type of flow control used by the device and CPU. The
extender supports RTS, CTS, DTR, and DSR. Some systems may
require a wiring adapter to transfer RI and DCD.
Attach the device directly to the serial port on the PC and test whether
the problem is a PC or extender problem.
Some serial devices cannot be hot-plugged. Try connecting the device to
a powered Remote Unit prior to booting the system.
