Dow Jones Portfolio Evaluator was designed to work with the Communications
card; however, it also works fine with the Super Serial card after you make the
change listed below in the DJPE program. The Communications and Super Serial
card differ in these three ways:
* The location of the status and data registers are different.
* The status register bit arrangement is different
* The Super Serial card is switch dependent, while the Communications Card
must be programmed entirely in software.
Place your Super Serial in slot 2, and then set its switches to:
switch: SW1 switch SW2
1 2 3 4 5 6 7 1 2 3 4 5 6 7
1 0 0 1 0 1 1 1 0 1 1 0 0 0
Note: These settings are not the same as for Dow Jones News and Quotes.

5710 ST=49321: rem addr of SS status
5720 DA = ST - 1: rem addr of SS data
5730 print : print chr$(4)"pr#2": print chr$(24)
5740 print chr$(4)"pr#0
5780 for I = 1 to len (I$):wait ST, 16: poke DA,
asc(mid$(I$, I, 1)): next I
5840 I = peek (772): if I = 8 then I = 1 : rem err flag
3. Save Login
4. Load Fetch
5. Unlock Fetch, then make these changes:
6910 wait ST, 16: poke DA, 17: rem Xon
7120 if IN = 1 then wait ST,16 : poke DA,19 : run
7200 if 5 * int (S / 5) <> S then wait ST, 16:
poke DA, 17: goto 7360
7300 wait ST,16: poke DA,17: rem Xon
7900 ST=49321: rem addr of SS status
7910 DA = ST - 1: rem addr of SS data
7920 print : print chr$(4)"pr#2": print chr$(24)
7930 print chr$(4)"pr#0
7970 for I = 1 to len (I$): wait ST, 16: poke DA,
asc ( mid$ (I$,I,1)): next I
8030 I = peek (772): if I = 8 then I = 1: rem err flag
6. Save Fetch
7. Bload Com22.obj
8. Unlock Com22.obj
9. Call -151
10. Enter 341:8 N 343:A9 N 34C:A8
11. Bsave Com22.obj,A$300,L$B1
