Short: Null Modem Sim V1.0 - Networks Emulators Author: fw@well.com (Frederick H. G. Wright II) Uploader: fw well com (Frederick H G Wright II) Type: comm/misc Version: 1.0 Requires: Any Amiga Architecture: m68k-amigaos Null Modem Simulator -------------------- General description ------------------- This driver simulates pairs of serial ports interconnected by null-modem cables. It can be used for testing comm programs and network software, but the primary motivation was to allow linking network software on an emulated computer (e.g. Mac emulated by FUSION) to Amiga network software. NOTE: This is a true null-modem simulation, not a simulation of two modems connected to each other as in nullmodem.device. The ability to network in this fashion provides a number of benefits, albeit not at blinding speeds: 1) Emulated and Amiga-native network software can share the same dialup link. 2) Ethernet cards that don't work correctly under the emulation can be used via the Amiga's network software. 3) Third-party serial cards that don't work correctly under the emulation can be used via the Amiga's network sofware. 4) The native serial port can use Miami's built-in driver, which tends to work better than serial.device or any of its replacements. 5) Incompatibilities between the emulation's Ethernet support and Open Transport on an emulated Mac don't preclude using Open Transport on the Amiga's Ethernet. Features -------- Sufficiently compatible with serial.device for most applications. Fully NSD-compliant. Supports up to 32768 simulated links. Capable of transferring at high speeds when applications use large IORequests. System requirements ------------------- Any Amiga. The driver should be compatible with all CPUs and OS versions. However, CPUs with caches require V36 (2.0) or later.
