DOS ain't dead

Hi,
I got this PCMCIA network adapter
http://rayer.g6.cz/1tmp/asekol4.jpg
and I'm looking for usable packet/odi driver for DOS. I googled hard and found in archives only drivers for Pro PE2000 and PE200 that doesn't work. I found only Windows driver for PE1500 that consist of TX100NDS.SYS and OEM7.INF. This driver works fine under Win98.
Maybe someone luckily have/had this card and may have a driver diskette somewhere, plaease look for that if so...

IF not, try search internet for "TX100NDS.SYS"
Hope this helps. :)

Thanks, you're my hero! :)
I found, that there was not problem in packet driver itself but PCMCIA enabler (a real mess of various manufacturers under DOS). I found that if I load packet driver for ActionTec PE200 under Win98 where I pass args of IQR and port acquired from devmgr then the driver loads OK displaying right MAC. But not under DOS with same args. Then I tried enabler (lanen.exe, 11483B) from your link and voala, packet driver loaded successfully. landiag also passed. So I uplpoaded doslinks on this old Toshiba Sattelite 470CDT and kicked up the network connection and just sending this post. Hope it doesn't crash :)

So when I tested the eth. card is working I got an idea to push it into ancient wonderfull HP 200LX (PC XT) handheld (it has one PCMCIA and people used it with some modem and ethernet cards). I found alternative OpenSOurce enabler LXCIC.COM and packet driver LXEN2216.COM specially made for 200LX. The driver loaded OK and reported the right MAC.

Then I use LXTCP and latest mTCP to run DHCP and some TCP tools but it failed to connect DHCP. Even If I write IP addresses into config file manually utilities doesn't work, e.g. ping timeouted...

If I copy my mTCP setup to the old Toshiba NTB mentioned above and run enabler suggested by BW and packet driver for PE200 (this driver and enabler don't work on 200LX) it runs fine, even there are also lost packets it got address from DHCP within 1 second and all tools worked as expected.
Only one minor issue was that mTCP complained about DHCP lease time was less than 3600 (was 3200) so I have to manually edit tcp.cfg to increase the lease time. I would rather display only a warning than stop the functionality but maybe it can be configured too.

Do you see what is the problem? Should I try to play with MTU size or what else? Anybody experienced networking on HP 200LX here?

Just for giggles please try to use software interrupt 0x66 instead of software interrupt 0x60. It should not matter, but every usage of the LXEN2216 driver shows it using 0x66. (Don't forget to update the mTCP configuration file too.)

This setup is known to work with mTCP, or at least it did at one time:

http://www.vintage-computer.com/vcforum/archive/index.php/t-38300.html


Does anybody have the source code for this driver? It's based on the Crynwr framework so source code is supposed to be available, but I have not found it yet. Seeing the return codes in the packet driver source code would be nice.

Just updating everybody else on the debugging that has been happening in private:

The incoming packets do not look to be valid. mTCP gets an error from the packet driver every time it tries to send a packet. I strongly suspect that the Ethernet card is bad.

I've asked RayeR to try one of the 16 bit WatTCP based programs as an experiment. If anything can work with the card then I know I have a problem with mTCP, but I also know that mTCP has worked with this combination before.

I tried with an old 16b wattcp from 1992 and lxtcp packages but it doesn't work. Neither with manual IP config neither via DHCP. Ping or other program just timeouts. Only what works is displaying MAC address by TCPINFO. There's no diagnostic tool like pktool. So maybe the ethernet card is not fully compatible with the packet driver or some IRQ problem? I cannot specify IRQ as parameter for driver it's probably hardwired in HP 200LX and in code). But in that case I would expect that any packet would arrive not damaged ones...
