Hello, Regarding running os2 (communication-)programs and dos programs at the same time: When i entered dosmode from Presentaion Manager i noticed that communication programs in prior sessions came to a halt. I found that this problem is dependant on what you start first. When i start binkley first and then goto dosmode binkley stops dialing and my modem will not respond to any 'at' strings. If i go to dosmode first and then goto PM again (CTRL-ESC) and start binkley everything goes ok, even when i return to dosmode binkley remains active. Strange??

Its a matter of priority, literally. PM apps default to Always High priority, while Fullscreen apps default to Regular. The Beta BinkleyTerm gets around this now by always switching to Class Always High, level 31, whenever it fires up the MODEM routines. Works wonderfully, got a lot of 99% to 100% efficiency file transfers today, in the background, while running a 3270 CUT emulator in the foreground. Actually, the Janus transfers were more like 125-130%, but mostly small message archives.

>This shouldn't happen, so something is wrong here :-) >Does this happen with ANY dos program, or are you trying to run >something that takes over the comm port? (perhaps without >your realizing it.) Hello, Let me first thank you for your reply. Dosmode on my computer means that Fixed Disk Organizer (IBM) is started. From there i can select programs. Say i am using TP 5.0 and calling a bbs, my modem shuts down. Perhaps you will read another message of mine, i found that the problems only occur if i go to dosmode AFTER starting a com program. >Also, what type of a system are you running under- which version of >OS/2, and how much system ram do you have? These factors might be >relevant in trying to pin down your problem. My system is a IBM model 70, 4 MB Ram. I am running under OS/2 version 1.1 EE.

>When i start binkley first and then goto dosmode binkley stops dialing >and my modem will not respond to any 'at' strings. Works fine here, though I have noticed that file transfers in Binkley are substantially more "fragile" when the compatibility box is the foreground task.

PF> Do you have a 286? Switching from prot mode to real mode on a 286 PF> is a real scarey kludge. The keyboard controller resets the cpu PF> (!), part of the POST code checks some flag in memory, and skips PF> the RAM Test etc, and JMPs to some saved location. Unless you're PF> receiving characters at 2400 bps or less, you are almost certain to PF> loose characters. It might even happen at 2400. Wait a minute. I did some testing of comm overruns on an 80286 (for the OS/2 comm article I did for Byte a couple of years ago), and found that an 8MHz standard AT could keep up at 9600 bps with no loss of data - even with two other tasks running, including one in the DOS box. I found NO loss of data until I pushed the data rate to 19200, where the AT was no longer able to keep up. Certainly, it is possible to load up the machine enough to cause overruns, but you can do that on any computer. Even considering the mode-switch kludge, the 80286 (in its AT environment) does not have any innate trouble handling lower baud rates. Of course, it's also important that the communications code take proper advantage of large DosRead buffers (for the comm handle), multithreading, and appropriate use of priorities. It is quite possible for a communications program to compete with itself for resources if it is not carefully constructed. This could result in data overruns. Anyway, don't be too quick to blame the 80286. -- Jim Gilliland - via FidoNet node 1:140/22 UUCP: alberta!dvinci!weyr!157!200.34!Jim.Gilliland Internet: Jim.Gilliland@p34.f200.n157.z1.FIDONET.ORG Standard Disclaimers Apply...
