The problem is the Linux pty driver.
To impliment a working remote serial port, you have to write a
kernel-mode serial driver -- and that's a lot of work. [Writing
one isn't bad, maintaining one is a complete bitch due to the
way the infrastructure keeps shifting out from under you.] I've
proposed fixing the pty driver to allow it to emulate a real
serial port, but that proposal wasn't well accepted by the
powers-that-be in the Linux kernel world.

I wanted merely save some time and have more comfort during programming PICs.
Writing kernel driver for (emulated) serial port is would take much more time than I can ever save by it.
I will probably try it once I have some spare time anyway )

Until then I stick with programming over ssh ;p
