That might be OK for the Unix/Linux people out there, but it's absolutely useless for Windows users (running QEMU on a Windows host), for whom socat, ptys and character devices are mostly meaningless concepts (unless you have some sort of Unix/Linux background). I'm trying to promote a more universally usable method in connecting via Telnet to the serial port - it works nicely for SIMH whether it's using a VMS, PC or Unix platform as a host. Even Microsoft decided that Telnet was worth having ! It would also be useful for anyone wanting to port QEMU to other O/S environments that do not have a Unix-style runtime environment, device files, etc. Almost anything that supports TCP/IP can offer up a port for a Telnet connection, including many embedded environments. Today, QEMU's guest machine implementations are mainly Unix-style environments based around workstation / PC / Pocket PC hardware platforms. One day, QEMU might also be a great dynamic translation / emulation environment for some more esoteric embedded devices, maybe along similar lines to MAME / MESS, and it might be running on more scaled-down host platforms rather than multi-GHz PCs with 512Mb or more of RAM. How about QEMU hosted on PS2/PS3, Xbox or PSP ? OK, so maybe I exagerate, but you get the idea !
