I agree with Mitch, the size of it is insignificant. Even without any tuning and integration with existing code, the dictionary only grows by about 2400 bytes for the 5248 byte source file. If you think it will be useful, we can add it. -- James Cameron http://quozl.linux.org.au/ __

XO-1.75 OpenFirmware serial terminal

2012-03-27 Thread James Cameron
This is a serial terminal implementation for an XO-1.75 using Open Firmware. Allows a laptop to be a host for a target laptop through a crossover cable. Use cases: - field diagnosis when a computer with a serial port is not available, but adequate quantities of XO-1.75 are available, - diagno
