I am running Windows NT 4.0 with SP5. It is a relatively new install. However, when I finally got around to using my modem, I ran into a particular problem. Certain programs could use my modem fine, such as Network Dial-Up, Hyperterminal, Winfax Pro. But other programs, like Telix, or Searchlight BBS (I tried both the DOS, and the 32bit Windows version) would generate the following error:
"The system cannot open COM1 port requested by the application" and it gave me the option to Terminate or Ignore.
I have used these very same programs in the past with the same version of NT, without a problem. I tried reinstalling NT and attempting the programs both before and after I patched it with no success. Does anyone know what causes this, and how I can correct it? Thanks!
