Modem connection timer.
Lost receiver ready timer.
No-activity timer.
Host control of every card output modem
line.
Communications Mode: Asynchronous, bit serial.
Break Detection:
Break conditions are recognized by the
card and cause interrupts to the host. The
MUX can also generate break conditions
as they are needed. A break
is
a "space"
condition for two consecutive character
times.
Optional Handshaking: All handshaking
is
optional and
programmable. The protocol characters
are also programmable. Device controlled
XON/XOFF
is
performed at the card
level.
The MUX passes edit functions (i.e., backspace, character delete, etc.) to
the host. They are then managed by the host operating system.
