Hi, Using minicom, I have isolated the slow serial line problem to computational load. On my 1+, which is a pretty slow machine, I can run the serial port at 19200 and 38400 without any problems (both hardware and software flow control work) from a virtual console without X running and reall nothing else going on. From an xterm, I get serial overrun errors reported from the kernel. Also, if I start a tedious process (such as a find process), this screws up everything and I begin to get serial overrun errors too, even without running X.
Apparently, the serial lines only work properly at high speeds when there is no computational load, since even just running X (which takes 20% CPU on my machine) causes serial overruns. I still don't really have a way to get around the problem though. Any ideas here are appreciated. By the way, has anyone tried high speed serial (19200 or 38400) on an IPC?
