onboard memory

DMM>It's doing it in all my dos session, yes virtual memory,

Open the settings for your dos session and you can set EMS, XMS and DPMI
memory to however much you want.

DMM>but another problem. System shouldn't be locking up the
DMM>way it is when both nodes start downloading at same time.

Check that your two COM ports are using IRQ's of their own, that you
aren't trying to share them with sound cards, net cards - what have
you. Also, if the connects are >2400 baud, make sure you have 16550
UARTs in the serial ports, the old unbuffered 8250's can't keep up.

DMM>It never did it before until I went to OS/2 warp.  Another,
DMM>how do you get OS/2 Warp to report the correct amount of
DMM>memory?

What were you using before?  What do you mean the correct amount of
memory?  OS/2's free memory is the amount of system ram + the amount of
free space on your swap drive less about 2M for the kernel, 1M for every
DOS session and 2M for every windows session.  Seems to me there is a
system reporting and diagnostic tool included with warp that should tell
you what you want to know, although I don't know how useful you'll find
that information in a virtual memory system.  If OS/2 needs more memory,
it swaps stuff and voila, it has more memory!
