b. Make sure that have a good cable connection between your serial device and the Serial
Device Server. If possible, try a different cable.
c. Make sure that the cable pinouts are correct. In order to communicate properly, the
transmit data line on the Serial Device Server must be connected to the receive data line
on your serial device, and the receive data line on the Serial Device Server must be
connected to the transmit data line on your serial device. Modem signals, if any, must
also be connected so that input signals are connected to output signals and vice-versa.
Refer to the cable diagrams in Chapter 2 of this manual.
d. Try printing a test page (if your serial device is not capable of directly displaying ASCII
character output from the Serial Device Server’s serial port, then disconnect the device
and connect a serial printer or terminal to the Serial Device Server). If the test page
prints OK, then the serial port on the Serial Device Server is working properly. If it does
not print, then double check steps 3a, 3b, and 3c.
