[DSP-10] Problems Loading UHF3x35A.HEX

[Bob Larkin]

Hi Rich,

I just was chatting with Mike on 75-m.  We both thought it would be 
worth mentioning that a very basic test is to leave JP1 open, selecting 
flash bank 0 (the monitor) and powering up with the RS-232 hooked to a 
PC with a 9600 baud terminal program.  You should see three identical 
lines of ASCII sign-on, starting with "!!!  ADSP-2185 Monitor ..." 
Also, this should result in the red LED flashing slowly.  If you send 
"$$$" from the terminal, you should receive back "okxy" where x can be 
anything, and y is an ascending ASCII character that is "0" the first 
time. This involves none of the DSP-10 hardware, of course.

Also, on the flash chips, hold on to them as I have more and they may as 
well be spread around.  Those you have probably came to me from KC7WW 
with the idea of getting them used.

  Good luck!  Bob  W7PUA

When I attempt to load the Hex UHF3XXX.hex, using FL1B.BAT, I am getting a COMM error on all ports. This is what originally led me to believe my monitor maybe suspect. I have checked my computers com port and it appears to be functioning fine. The MAX232N also appears to be operating normally. As I look through the schematics, I see there is a TXD and RXD line, but I cannot see with these schematics where it goes. I would like to take a look at the device the MAX232N connects too, so if someone can help me there that would be appreciated.
