Function xn_autoanswer

xn_autoanswer waits for an incoming call and establishes a physical modem connection.

int xn_autoanswer(int    iface_no, 
                  char * setupstr, 
                  word   timeout, 
                  char * term_str);

Parameters

iface_no

Interface number returned by xn_attach.

setupstr

The modem initialization string (e.g. "ATZ0").

timeout

Number of seconds to wait.

term_str

Line termination string for sending modem commands (usually "\r").

return value

Returns 0 if successful, otherwise -1. If an error occurred, call xn_getlasterror and xn_geterror_string to return the error value. Section Error Codes further describes each error.

Possible values for this function are:

Value	Meaning
EBADIFACE	Invalid interface number (RTIP-32 specific).
EMODEMNORING	No ring received in specified time (RTIP-32 specific).
EMODEMBADRESP	Unexpected response from modem (RTIP-32 specific).
ENOTINITIALIZED	RTIP-32 has not been initialized (xn_rtip_init has not been called).
ENOPKTS	Out of DCUs.

If the function returns 0, a physical modem connection has been built up. xn_autologin can then be used to connect to a remote host.
