8.2.1 Dump mode
When the
DinBox PSTN(485)
receives a character from the DTE, during the call setup
and/or speed negotiation, the modem will stop all further negotiations and will go off-line.
We have added ‘dump mode’ to prevent this.
atk1
stop negotiation when a character is received
atk0
dump mode active
8.2.2 Leased Line configuration
It’s possible to configure the
DinBox PSTN(485)
modem as a 2-wire leased line modem.
This point-to-point setup has always an originate and an answer side.
What do you have to know before you start configuring the modems :
Specification of the DTE port :
If asynchronous
what is the used speed ?
eg. 9.600 bps
data / parity / stop bits ?
eg. 8 N 1
flow control ?
eg. RTS/CTS
is DTR supported ?
If synchronous
is DTR supported ?
To configure the modems you can use a standard terminal software package. If the DTE uses
asynchronous communication it is very important to use the same baudrate as the DTE port
when the modem is configured.
This asynchronous baudrate will be saved when the modem receives the AT&W command.
