- Well, I have posted here quite a few times about Using the modem
- under OS/2, and many people have provided advice, and sadly none has worked.
-
- My problem:
-
- I have a 486/33DX, 8megs ram, 210 meg HD, 256k Instruction Cache.
- Whenever I use a DOS Communications program (ie, telix, procomm, and
- a HOST of others!), all my other DOS tasks become basically frozen,
- and If I want to download in the background, I have to be hitting keys
- in the windows of other tasks. So, If I run procomm or whatever,
- start a transfer, and switch to another DOS session, ie, a compiler,
- I have to hold down a key to get it to do some work. This is extrememlu
- annoying, inasmuch that I can really only have one dos comm task, and one
- regular dos task running -- the rest are frozen until the transfer ends.
- Even some OS/2 native apps become frozen.
-
- I did do things like setting IDLE_SENSITIVITY to 100, and IDLE_SECONDS
- to the max, but this doesnt work.
-
- My modem speed is 2400. this problem occurs at 300-2400 baud. It is
- insanely ridiculous. I have duplicated this problem on a 386/25
- with 8 megs ram. When I have a dos comm prog going, and doing a download
- both machines perform about the SAME. (wow!). I am NOT over commiting memory,
- as my DOS taks have 0 dpmi mem, 0 xms, and 0 ems, and 640k of "regular
- mem". It doesnt matter how many apps are open .. 2 or 10! .. the performance
- is the same: extra slow. Alot of OS/2 progs are fine, but like I said,
- some freeze until the transfer is over.
-
- This problem may cause me to get another OS. I like OS/2, but I find
- it inexcusable that it does this kind of stuff at LOW modem speeds.
- I might have to get MSWin or something, because I have used it doing
- the same things, and I have no problem. I wish ibm would fix this.
-
- Also, I have tried the SIO drivers, but they didnt work well.
-
- One possible thing I thought of is that the comm programs may write
- every block to disk, thus causing major device lags. However,
- may HD light doesnt go off often enough for that.
-
- Someone, please help, and Hopefully IBM will do something. I am not going
- to spend hundreds of dollars to get a modem with nifty buffering chips/
- If OS2 cant handle modems that dont have 16550s even at 300
- /1200/2400 baud on a *486*, its not very good.
-
- However, I am hoping there is something that can be done.
