- I have a question about OS/2 & DOS Comm programs.
-
- Whenever I run a DOS comm program (ie, telix, telemate, procomm, etc),
- and start downloading a file, My other DOS tasks crawl to a halt.
- It takes about 40-50 seconds to get a dir of the root directory (has about
- 15 files in the directory I dir). And this is with NO other programs
- running except a dos command.com, and the term program. Its ridiculous!
- I have a 486/33, 8 megs of mem, and a 2400 baud modem. (256k ram cache)
-
- Now, someone told me to "start my other apps first, then start comm program."
- that had no effect. DOS tasks were still ungodly slow.
-
- Someone told me I needed a 16550 UART (buffered) chip. Is this so?
- (havent checked this out). If so, I am going to be severly angry with
- OS/2 that it cant handle a stinking 2400 baud modem without buffering
- hardware. I know MSWindows can do my download in the Background, and
- my foreground tasks are unaffected, and everything is smooth
- (like I said, 8 megs, 486/33, etc). What the heck is OS/2's problem?
-
- Also, this problem carries into some OS/2 tasks. Nice OS/2 programs
- (ones that are polite priority wise), such as Brief 3.1, will hang
- until the transfer is over when I tell them to exit, and they take
- forever to load. Normal OS/2 programs are virtually unaffected,
- but it IS annoying to have programs LOCK waiting on the damn 2400
- baud transfer to finish. OH, and it does this at *1200* baud as
- well. That is another reason I am mad at OS/2 -- at 1200 baud transfer
- will lock slow the machine down. OS/2 runs smoothly otherwise.
-
- How does IBM hope for OS/2 to succeed when It cant handle 1200/2400
- baud communications. Maybe its just my copy of Os/2. I am using the
- beta Version, however, the original 2.0 had this very same problem,
- so nothing has changed performance wise going from 2.0 to 2.01 beta,
- in the modem respect.
-
- PLEASE HELP. Hopefully someone from IBM will read this and tell me
- what the hell is up. Totally ridiculous that I cant have transgers
- at 12/24 baud, and still use my machine to do other things.
