My MS-DOS program writes to COM1 (it sends a short string
for opening a cash drawer attached to COM1). When run in
Windows XP, it always responds 'not ready'. A technical
colleague investigated and says that both DTR and CTS
lines are reported to an MS-DOS program running under
Windows XP as "low" even when they are "high". My MS-DOS
program is from a third party, so there is no way I can
alter it (eg to have not bother checking the COM1 port
status before sending the Open string). How can I get
this program to work properly in Windows XP?
