I developed a software in Visual Basic 6 to operate parking lots. The software
emits entrance tickets, cashing, barrier operation and controls credited
I found out VB6 had a limitation to operate serial ports, for it can't operate
16 ports at a time. In certain times it loses complete control of some of the
ports and you can not determine its actual state, nor even send or receive
I've modified my software to be able to manage the serial port operation with
Port Series Control. This solves VB6 limitation on MSCOMM32.OCX and allows me
to operate up to 255 ports. It also solves the lost of control of the ports.
The modifications to replace the use of MSCOMM32.OCX for Serial Port Control
of FabulaTech are minimum; this includes a few lines in the code without
getting into API programation.
