POINT
(1) MX Component is not compatible with manual line connection (connection via
an operator).
Use a subscriber telephone line or private telephone line to perform modem
communication.
(2) It is required to set the COM port when performing modem communication by
using modem built in the personal computer or the PC card (PCMCIA).
For the COM port of the modem built in the personal computer or the PC card
(PCMCIA), refer to the manual of the corresponding product.
(3) For modem communication, the AT command, that is standard for some
modems, is not executable.
If the line cannot be connected by selecting "Modem standard" for "AT
command" within the communication settings utility, specify the AT command
on the user side.
Refer to Section 5.1.7 for the setting of "AT command" within the
communication settings utility.
(4) When using the callback function, use the Q Series Corresponding C24.
