s16a_serial_str

Description

Send a command string to the Analog Input Module. Read the response from the AIM and return it only if it differs from the command string sent. Otherwise return NULL. This routine is especially useful for command strings, which echo the command string, unless an error occurs.

Syntax

char *s16a_serial_str(S16aDev *s16a_p, char *str);

Arguments
s16a_p	S16A device struct, returned from s16a_open
str	Null-terminated command string to send to the Analog Input Module

Return

NULL indicates a response string that matches the input command string, which indicates successful transmission. Otherwise, this routine returns a pointer to a string containing the characters received in response to the command string. The response string is in a single buffer allocated by the library. Therefore, if you need to preserve the response string, you must copy it to another buffer before making another libs16a.a library call. Sets errno on failure.

s16a_serial_write

Description

Send a command string to the Analog Input Module.

Syntax

int s16a_serial_write(S16aDev *s16a_p, char *buf, size);

Arguments
s16a_p	S16A device struct, returned from s16a_open
buf	Array of characters containing the command string to send to the Analog Input Module
size	Number of characters in the command string

Return

Success: number of characters transferred; –1 on driver error. Sets errno on failure.
