TTYDSP
TTYDSP was a software/hardware combination that converted a NeXT computer's DSP into a high-speed asynchronous RS-232 port. Capable of speeds up to 128,000 baud, TTYDSP emulated a NEXTSTEP tty driver which provided compatibility for a wide range of communications applications, such as SL1P/PPP and UUCP.
High-speed modem and ISDN users appreciated TTYDSP's efficient use of the DSP, increasing throughput and reliability while decreasing main CPU load. TTYDSP was available only for NeXT 680x0-bascd hardware with the 56001 DSP.
