Null-modem Doom?
Brian A. Willette
A friend of mine and I tried to hook our computers up through a null
modem (comm 4 on my DX266, com 2 on his DX2-50). The connection was
established fine through DOOM, but when the game came up, It moved so
slow we would hit a keypress and wait 2 mins before it would jog
slightly. We tried a terminal program to make sure our connection was
ok and it was. we even transfered files back and forth. Anyone offer
any insight as to what might cause this? We think maybe since I have
VLB and he doesn't, that might do it?
Thanks,
Brian Willette

I don't have any insight into this problem, but I've also had some
problems once connection has been made. Using a 486/50 and a 386/33,
with a null-modem cable plugged into the mouse ports on COM 1, I made
the initial connection just fine. However after just a few minutes of
fun, the reaction time started to slow down and after five minutes or
so, it became totally unplayable. Saving the game and restarting it
sets it back to full speed for a few minutes before the problem repeats.
I'm using an original shareware version 1.0 that was first patched to 1.1
then to 1.2.
Is anyone else experiencing this problem? Any solutions?

My friend and I have a null modem setup (486/33 and 386/33) which works
fairly well, but it does appear that the speed is reduced quite a bit from
single player mode. Do we need to 486's or is the software not using a
faster data connection (9600...)?

slow as to be unplayable.
This upsets me as the only way I can tempt my girlfriend into DOOMland, is via cooperative mode :(

I played for 6 or 7 hours straight this past weekend and we had no problems,
slowdowns, or shutdowns whatever. We had to 486 SLCII 66 hooked up via
null modem cable and it played as fast as single player.

My friend and I tried hooking up our computers (mine 486DX33VLB, his
a 386DX25) via null-modem cable; it worked at first, but after a few
minutes of play, it just slowed right down. I think it slowed down
right after somebody killed the other. Could this be a source of the
problem?

was wierd how we had to set it up. We had to boot a comm program (Telix
in our case) and have the other computer start the sersetup program.
When the PLAY0_0 came through, we dropped the comm program through a
shell and the other user ran setup and chose serial link. Seemed to
work ok. VERY odd. The problem seems that my friends comm port was
transmitting through the serial port at 2400 baud. Dunno why.

What UARTs do ya'll have? I tried null modem connection (although with
a 486dx2/66 & 386dx/25) and it works great for the first minute or so,
but then slows down more and more as we go along...after about 5 minutes
its completely unplayable.
Both 8250 UARTs...

Yes, good point. I posted about this as well, and my roommate and I
both have 8250's. On ours, the slowdown is limited to a fixed amount
(ie not rendered unplayable, but still slows down so much as to be
annoying). The big question is, why does it work well for a few minutes,
and what is the trigger that causes it to hit the slowdown? Has anyone
written to ID about this, or could provide me with an e-mail for 'em?
Thanks - too hard to brass-knuckle the opponent with a choppy screen.

| And now a few thoughts to brighen up your day...... |
| |
| The program is absolutely right. Therefore the computer must be wrong. |
| Computers are useless. They can only give you answers. |
| Asking whether macines can think is like asking whether submarines |
| can swim. |
| If a program is useful, it must be changed. |
| If a program is useless, it must be documented. |
| There are two ways of constructing a software design. One way is to |
| make it so simple that there are obviously no deficiencies and the |
| other is to make it so complicated that there are no obvious |
| deficiencies. |

Well, I would think that the port somehow fills...maybe since doom hates
flow control, it doesn't care wether or not its ready (other games allow
flow control, and therefore they work at 19200, 38400, 57600,ect w/o
slowdown), and the 8250 UARTs can't take care of it. So, I believe the
only way to fix it would be to either have id recode to use flow
control, along with all the goodies they decided to kill in the modem
play (such as baud rates, compression, error correction), or we could
get 16550s. I'm not really sure about this, but this seems to be whats
happening. Thats why it would take a while to slow down,
the ports could take it for
a little while, and would slowly fill. If we slow down the baud rate
(if doom will allow it), I can only assume that the port will not fill
or fill much slower (the UARTs can hack it?)...Don't know what to do,
but I'll see...Someone emailed me and mentioned some program on an FTP
site. Maybe if we connect with a comm program over the direct link at
something like 4800 baud or so, and then shell out and run doom in modem
mode (already connected) it would work. I'll check.

I'm playing doom 1.2 through null modem wire.
It works very well ( I mean very fast )
I have a 486 sx 33 and 486 dx 40.
If you want any information about my config mail-me.
