I have bought a modern PC and BayCom does not run on it!
During the last three months we have been reported some problems
with RS-232 cards using the fast 16550 chips with internal FIFO
instead of the "traditional" 8250 chip. There seems to be a number
of 16550 versions (not all of them!) which do not support the
internal 6 bit mode of the RS-232 we use for clock and baudrate
generation in the BayCom terminal. This mode is rarely needed for
other applications and it looks like chip designers have not
implemented it on these chips.
As a consequence, BayCom will not run on these PCs. Unfortunately, there
is no easy workaround, so we could not solve this problem yet. We will
try to fix it with the next version.
If you run into trouble, buy a simple 8250 card for < 10 US$ and put it
into your PC as COM3/COM4 and configure BayCom on it. Make sure,
that addresses AND interrupts are set properly as configured in
the INSTALL program.
We would have some interest to know, which of the 16550 do not run.
Currently, National Semiconductors are the only one's known to us.
If you have a trouble making card, please mail the name of the
manufacturer of the card and of the 16550 chip on the card to
baycom@baycom.org. Thankyou!
