| SVDM is a MODEM emulator for Windows which utilizes the Synchronet Virtual UART/FOSSIL Driver (''DOSXTRN.EXE/SBBSEXEC.DLL'') to enable support for DOS communications programs on Windows NT-based operating systems. 64-bit Windows support is enabled by also installing [[http://www.columbia.edu/~em36/ntvdmx64.html|NTVDMx64]]. | SVDM is a MODEM emulator for Windows which utilizes the Synchronet Virtual UART/FOSSIL Driver (''DOSXTRN.EXE/SBBSEXEC.DLL'') to enable support for DOS communications programs on Windows NT-based operating systems. 64-bit Windows support is enabled by also installing [[https://mendelson.org/ntvdmx64.html|NTVDMx64]]. |
