Yes, VMWare doesn't support serial port using host's ttys any more. My idea is: [host - application] <- read/write -> [virtual serial port /dev/ttyFakeS0] <- read/write over virtual null-modem serial cable -> [host - real serial port /dev/ttyS0] <- read/write -> [VMWare - application] But today I've just bought an USB-to-Serial converter and made for myself a null-modem serial cable. I use this null-modem cable to connect /dev/ttyS0 (native serial port) to /dev/tts/USB0 (USB-based serial port). My VMWare now can use one of those devices and the host use another one. Now above figure can be re-drawn like this: [host - application] <- read/write -> [/dev/tts/USB0] <- read/write over physical null-modem cable -> [/dev/ttyS0] <- read/write -> [VMWare - application] Anyway, later I'll try to write a device drivers act as virtual serial ports and virtual null-modem cables.
