Trying to transfer database files via modem. I am using custom software for the transfer which works fine on all machines apart from 1.
Machine in question is a laptop running xp.
When I try to connect I get an error message headed "16 BIT MS DOs SUBSYSTEM"
The Error is: "The NTVDM CPU has encountered an illegal instruction. CS:93c9 IP:dee5 OP:ff ff ff ff Choose close to terminate the application.
There is a close and an ignore button. If I click on ignore I get the same message back again.If I click on close the application continues and the modem connects and handshakes but no files get transferred.

Can anyone tell me what this error message means please.

I'm not sure what it means but, is your hard drive set up with ntfs as the file system? and if so does the application work on any other ntfs system? Programs can be written to specifically tell it how to write data and perhaps your program only recognizes fat16/32. Not that this helps any but it might explain whats going on.
Good luck!
