Windows for Workgroups 3.1 and FTP System's TCP/IP Stack

SUMMARY

FTP Systems makes a TCP/IP stack called PC/TCP version 2.2 for MS-DOS-based clients. PC/TCP can run on Windows for Workgroups 3.1 as a second stack by using the PC-210 kernel over a NDIS driver. FTP has written two additional VxDs to support their stack on WfW machines; WFWFTP.386 and VPCTCP.386.

The WFWFTP.386 VxD corrects problems when attempting to access network drives from a PC that is running both WfW and InterDrive. More precisely, under WfW when MS-DOS attempts to find_next_ file (Interrupt 21H, function 12H) in a directory wildcard search on a redirected drive, WfW attempts to do the search using its VREDIR.386.

The VREDIR.386 cannot complete the directory search function call and returns a -1 (failure) directly to MS-DOS. As a result, the InterDrive redir never gets a chance to attempt the operation and the directories appear empty for the network drives redirected with InterDrive. This has been confirmed by FTP Systems.

PC/TCP version 2.2 has the ability to map NetBIOS names to IP addresses, and so can be used in a routed network, and works with MS ROUTER.
