48 RabbitLink (EG2110)
E.6 RabbitLink Console Function Call (prior to Dynamic C 7.20)
The RabbitLink serial console may be accessed via the serial port using the PROG IN
connector on the RabbitLink, as was done in Chapter 2 to configure the RabbitLink.
If RabbitLink firmware version 1.00 is being used, the function calls described in this
section will be recognized by the RabbitLink. Prior to Dynamic C 7.20 these functions
were in STDIO.LIB.
PrintToConsole
int PrintToConsole(char flag);
This function controls whether Stdio commands such as printf go to the RabbitLink
serial console in addition to the Dynamic C Stdio window.
PARAMETER
flag 0 – printf() and related commands work as normal
1 – printf() and related commands go to the RabbitLink serial
console as well.
RETURN VALUE
0 if successful, -1 if not.
SendToConsole
int SendToConsole(char *data, int length);
This function writes a binary buffer of a specified length to the serial console on a Rab-
bitLink. Any data are acceptable since the data will not show up in
the Dynamic C
STDIO window.
PARAMETERS
data A pointer to the data to be sent.
length The length of the buffer passed in data
.
RETURN VALUE
The actual number of bytes written to the console.
