Ethernet Modem Mode
This mode allows Data Terminal Equipment (DTE) to control the NETRS232 using the conventional modem "AT" com-
mand set. In this mode, a DTE user is able to "dial" an IP address and TCP port. Incoming TCP connections are handled
under AT command set rules.
The standard serial port settings for bits per second, data bits, parity, stop bits, and flow control are available for con-
figuration, and should be set to match the DTE.
Modem settings include ECHO Enabled (E1), Result Codes Format Verbose (V1), Result Codes Display Return (Q0), Auto
answer (S0=1), DSR Control (&S1). Modem DTR control can be set to &D0, &D1, &D2, or &D3.
Applications: To provide the standard "AT" command interface to user applications that wish to communicate with
devices in an Ethernet environment. Remote console management that looks for AT interfacing can use this applica-
tion.
