Fax Mode Flow
Control Setting
Many facsimile software products use software flow control when the
modem is in Fax mode. Throughout our documentation, we recommend
that you use hardware flow control for Data mode (factory setting).
However, to allow compatibility with software products that use software
flow control by default, 3Com fax modems automatically change to
software flow control when entering Fax mode.
FCC Notice
FCC part 68, rules regarding fax operation, has been amended as follows:
Telephone facsimile machines identification of the sender of the message:
It shall be unlawful for any person within the United States to use a
computer or other electronic device to send any message via a telephone
facsimile machine unless such a message clearly contains, in a margin at
the top or bottom of each transmitted page or on the first page of the
transmission, the date and time it is sent and an identification of the
business, other entity, or individual sending the message and the
telephone number of the sending machine or of such business, other
entity, or individual. Telephone facsimile machines manufactured on and
after December 20, 1992 must clearly mark such identifying information
on each transmitted page.
