Ok if you can't tell yet I'm new to the SX/B compiler!

I loaded the September Nut's & Volts SX/B program on my SX Tech board (SX28), changed the:

FREQ 20_000_000

Baud CON "T115200" ' use with MAX232

to

FREQ 4_000_000

Baud CON "T9600" ' use with MAX232

 

because I did not have a 20 mhz resonator on hand and I like to work at 9600 baud. Compiled the program and programmed the chip. Program worked as described. Yea! Proceeded to the next step of changing the program to run on the SX52 Proto board. Changed the Device and Freq lines to the following:

DEVICE SX52, OSCHS2, BOR42

FREQ 50_000_000 

Compiled the program and programmed the chip. This time, running on the SX52 Proto Board, when you issue the "V"+<CR> command (version information - prints a text string), the program prints the Carriage Return and line feed, however the text string:

Version:

DATA CR, LF, " PC_PORT16 Version 1.0", CR, LF, 0

prints on the new line but the character column does not increment (each character that the SX52 sends out prints over the top of the last character. 

Using a Port monitoring program reveals that the SX52 is sending out 250+ character ASCII Decimal 13 (Carriage Returns 0x0D) and then the next character in the string.

What else do I need to change or add to make this work on the SX52 Proto Board?

I have attached a copy of the orignial September Nut's & Volts SX/B program and my modified version. 

Thanks in Advance,

Mike
