My company runs a DOS database that requires daily updating. These updates are done via modem, transfering all new files in from the UNIX box at the other end, then change processing after disconnect.
This program runs solidy in W95, W98, WNT4, and Wme with some adjustments for file handles and print buffers. In NT4, these adjustments are made in the CONFIG.NT file; in W98 and W95, in the CONFIG.SYS file, and in Wme in the 386Enh section of the SYSTEM.INI file.
We have a problem in W2k. The program runs rock-solid until we use the modem to connect to the UNIX box. It will receive files for a short time, then the program abruptly quits…no error boxes, no indictations of anything at all amiss. It just disappears off the screen and quits. If restarted, it will continue to receive files in short sessions until all files are received, but this might take five or six restarts. When all files have been received, change processing takes place with no further problems.
Can anyone help us figure out why modem activity in our DOS program causes it to dump in W2K? Any help will be greatly appreciated.
