I worked on many projects, designing some firmware for modem or other TLC products.
Abstract
- Software development of data communication plants
- Development software for RS232 switch matrix
- Used C language under QNX (Unix like OS for 80x86 hardware)
- Development data communication utility with 8086 assembler
One of these was particularly interesting to me.
A RS232 switch matrix.
My first job was to study the QNX operating System to develop an interface to command a matrix Rs232 switch (DCX-A).
With this interface was possible to identify each Rs232 line to be handled by the circuit switching mechanism and to be connected easily with other lines.
