>From the docs (1993): "The Xircom Pocket Ethernet Modem is 'software driven'... does NOT currently support OS2, Unix PC environments or Apple computers." -It comes with software for DOS and Win3 only. "Redirection of the communications port under DOS is not supported using memory managers such as HIMEM/EMM386." -At various times I have confirmed this with MS-DOS, Open/DR-DOS, and FreeDOS. "The DOS redirector is compatible with Quarterdeck's QEMM memory manager, version 7.03 or later." -I also tried this, and while the drivers do load, the system is unstable with frequent exception errors. > Also, if you are using DR-DOS 7.XX, you can make some > drivers such as NWCACHE and NWCDEX run in extended memory, by > loading the DPMS driver first. I can try this, but with the small programs I am running and limited extended memory, I think I can make do without a disk cache. Most of the stuff I am using should (theoretically) run on an XT. > (BTW, I know nothing of parallel port modems.) I believe that this particular model (14.4 + NIC) sold for $400 back in '93. I picked it up for $60 a couple of years later when the original owner upgraded to Win95 (no drivers for that either). I used it for a few years on the laptop mainly for terminal dialup. I can avoid the hassle, by using a real external modem, but I have to cut it back to 9600 with the old serial port. I was also planning to try the NIC, instead of PPP over null-modem (slow), which I am doing now. Anyway, for this DOS "survpc", which I have only recently taken out of retirement, LSPPP's small memory footprint seems to be pretty important.
