gnupic: Thread: Re: [gnupic] gpsim USART + PC COM communication

Not sure, but if gpsim is talking to the actual hardware then it won't be a
*sim*ulator anymore.

No, that's not a fair response.

If I interpret this right, what is being asked for is to hook the simulated PIC USART to the PC USART so that the device you eventually intend to hook the PIC up to can be connected to the PC instead for development. Such a scheme used to exist for driving the PC parallel port from the simulation. There is currently no option for doing so with the serial port.

There was, at one time, a third party GPSim module that allowed a simulated "other UART" to be connected to a BSD pseudo-tty and thus to any application you chose. This was very useful in theory, but only worked on FreeBSD and NetBSD, not on Linux or Windows. It's also unsupported and doesn't work in recent versions of GPSim.
