Overview

This function is used by the SerialPort server, spd and included in the C client interface library, libspd.a.

It calculates the time needed to receive a character.

Functions

rxdelay

#include "rxdelay.h"

int rxdelay(int baud,
            int databits,
            char parity,
            int stopbits,
            int txdelay,
            int debug);

Calculate the single character receive time out value. The parameters are:

• baud is the line speed as a numeric baud rate.
• databits is the number of data bits per character.
• parity is the parity setting as O(dd), E(ven) or N(one).
• stopbits is the number of stop bits.
• txdelay is the number of mSec to delay before sending each character to a slow peer, such as a PIC-based device
• debug sets the tracing level. Zero is no debugging. 1 is useful for debugging the calling code as it traces the function call. 2 displays intermediate results during the calculation.

It returns the time to receive one character, rounded up to the next millisecond.
