There are similar solutions for Linux such as MODEMU (modem emulator) which has limited success when combined with DOSEMU (DOS emulator).
DOSEMU |
The original 1.0 release of Turbo Debugger for MS-DOS will run under simple MS-DOS emulators (DOSEMU, in an MS-DOS Window in Windows 95, 2000, etc.) The later versions attempt to control the underlying machine in a way not allowed by the host operating system (in which the emulator is running) and therefore do not work.
