RS-485 not separating bytes without external delay

Rabbit

I am using a BL2600 Single-board computer and am having trouble with the RS-485.

I have a simple program that uses RS-485 to send a command to another device (just transmitting, no receiving on this side). However, when I run it, it sends the data too fast, despite me setting the baud rate. I have to add 1 ms delays between the bytes to actually keep them separate. Here is my code:


#class auto

#define EINBUFSIZE 255
#define EOUTBUFSIZE 255

nodebug //??

void msDelay(unsigned int delay)
{
	auto unsigned long done_time;

	done_time = MS_TIMER + delay;
   while( (long) (MS_TIMER - done_time) < 0 );
}

void main()
{
	char highb, lowb;
	brdInit();
   serEopen(38400);
   serEwrFlush();
   serErdFlush();
   serMode(1);

   for(;;)
   {
   //G2P60
   if(!digIn(0))
   {
		highb=0x13;
      lowb=0x88;
   }
   else if(!digIn(1))
   {
		highb=0x27;
      lowb=0x10;
   }
   else if(!digIn(2))
   {
		highb=0x3A;
      lowb=0x98;
   }
   else if(!digIn(3))
   {
		highb=0x4E;
      lowb=0x20;
   }
   else
   {
   	highb=0;
      lowb=0;
   }




   ser485Tx();

   serEputc(0x00);
   msDelay(1);
   serEputc(0x02);
      msDelay(1);
   serEputc(60);
      msDelay(1);
   serEputc(highb);
      msDelay(1);
   serEputc(lowb);
      msDelay(1);

	ser485Rx();


   }
}

Without those "msDelay(1); " statements there, the bytes are not recognized as separate when I look at the output via Tera Term. Since I set the baud rate, and put these int Serial port E’s buffer, I assumed the buffer’s data would be sent at the correct baud rate with sufficient time between each byte, but I am apparently mistaken.

Am I missing something on how I am supposed to queue up commands to be sent on RS-485?
