#include <net_config.h>

void modem_init (void);

The modem_init function initializes the modem driver. The function:

• sets the default state of the RTS and DTR control lines if they are used
• initializes the driver status variables and buffers.

The modem_init function for the null modem is in the RL-TCPnet library. The prototype is defined in net_config.h. If you want to use a standard modem connection, you must copy std_modem.c into your project directory.

note

• The TcpNet system calls modem_init during its startup.

The modem_init function does not return any value.
