NAME
DESCRIPTION
1
/DCD
/DCD is an active low output from the modem. The AT&C command controls when the
XE2420 asserts /DCD.
2
/CTS
/CTS is an active low output from the modem. The modem asserts /CTS to indicate that it can
accept data from the terminal equipment on /TXD.
3
RESET
RESET is an active high input which intiates a modem hardware reset. RESET must be active
for a minimum of 100 milliseconds for a proper modem reset sequence. No external reset is
required; if none is used the RESET signal should be left open.
4
/DSR
/DSR is an active low output from the modem. The AT&S command controls when the XE2420
asserts /DSR.
5
/RTS
/RTS is an active low input to the modem. /RTS indicates to the modem that the host has data
to send.
6
/DTR
/DTR is an active low input to the modem. The AT&D command determines how the modem
will interpret activity on /DTR.
7
/RXD
/RXD provides the path for received data and modem responses to be sent from the modem to
the host terminal equipment.
