Couple questions about using ADTPro on a GS

[nyder <nyder.23@gmail.com>]

I decided to get my GS up and running.

Seems to boot up fine, says it's Rom 1, which is good I guess.

I'm following the instructions and video.

Since I don't have a SSC, I have to use the modem port.

I found a 9pin serial cable that plugs into it, then have a 9to25(?)
adaptor, a null modem adaptor, then a 25 pin to 25 pin cable, then
another 9 to 25 adaptor hooked up to my computer.

I run the adtpro software (latest version, downloaded it today), put
in the IN#2, then hit CTRL-A, and put 14B (which doesn't show, but the
cursor changes back from the ? to the *.

So, when I send the prodos, nothing appears on the GS screen like it
shows on the video.

I'm assuming my problem then is my serial connection.

Is that a logical assumption?  I know the video has an 2e and SSC
card, but i figured the display stuff would be the same.

But the vid doesn't use a null modem adaptor, even though the
instructions say to do it.

Can I use like one of the laplink cables instead?  I have a couple
that have both 9 pin and 25 pin connectors on each end, and I'm pretty
sure it's wired in Null Modem configeration.

I guess if I had to i could use my multimeter to see what pins are
connected to what in the mess i have, but i'm pretty lazy.  =)

anyways, I guess what's displayed on the video is pretty much what
i'll see on the GS, other then the SSC stuff, correct?

thanks for any replies and input
