SOLUTIONS:
1)
Check cabling between host device and H-
Series multiport. If the host device is a PC,
you may check the cable using the TERM
program. With TERM loaded on the
appropriate com port, all handshaking lines
should be high (except possibly DCD
which is not used). If the CTS or DSR lines
are not high, compare the pinout of your
cable with the pinout shown in Figure 1 on
Page 10. If lines are high, power down the
multiport. You should notice the CTS and
DSR lines go low. If they do not, there is a
good chance the cable is not correct.

Check the installation procedures for host
computer's serial port. COM1 must generate an
interrupt on IRQ4 (COM2 on IRQ3). Also, check
any jumpers for defining port configuration which
should be jumpered for DTE, not DCE.
