use cfmakeraw when setting up the serial line

Somehow missed that function at first. This makes serial I/O work on Linux.

add a second test

This one is designed to let us see when the chip reboots.

reduce serial read timeout to 100ms

Unreliable responses from the board are not due to being busy, but due to flaky serial receive code. If it missed our request, it will never answer, so better to fail (and try again) early.

README

MC5000                              README                              MC5000

DESCRIPTION
     An assembler and programmer for rickp's MC5000 dev kit.

     The MC5000 is a physical realization of the fictional microcontroller
     family from the game Shenzhen I/O by Zachtronics. It uses the low-cost
     Padauk PFS173 microcontroller.

     This program translates MCxxxx assembly to byte code and writes it to
     any of the MC5000 chips via the board's USB serial port.

USAGE
     Run 'mc5000 -h' for quick help.

     Refer to the supplied manpage mc5000.1 for details.

BUILDING
     Run make.

     The program is designed for a Unix environment, specifically OpenBSD.
     It has also been tested on Debian GNU/Linux.
