Appendix B High Speed Operations
This section describes the use of high speed capability supported by C114HI. There
are two speed spectra which are
Normal Speed Spectrum High Speed Spectrum
50 400
75 600
110 880
134.5 1076
150 1200
300 2400
600 4800
1200 9600
1800 14400
2400 19200
4800 38400
7200 57600
9600 76800
19200 153600
38400 307200
57600 460800
115200 921600
The corresponding speed in High Speed Spectrum is exactly eight times the speed in
Normal Speed Spectrum. A port, if set to Normal Speed Spectrum with 38.4K bps,
will work at 38.4K bps for sure; while a port, if set to High Speed Spectrum with
38.4K bps, will actually work at 307.2K bps (307.2K = 38.4K X 8). Choose either
one of the two speed spectra by running DOS utility: IO-IRQ.EXE.
*Hint: 1. Check what speed range is needed for a port.
2. If a port will work at speed slower than 400 bps, e.g. 75 bps, then
choose Normal Speed Spectrum by running IO-IRQ.
3. If a port will work at speed faster than 115.2K bps, e.g. 460.8K, or
at a special speed, e.g. 400 bps, then choose High Speed Spectrum
by running IO-IRQ.
