[comp.sys.ibm.pc] COM3 & COM4 board needed

mal@hjuxa.UUCP (LEACH) (06/26/89)

I need to purchase a serial board for an IBM AT compatable computer
that has at least 2 com ports and is able to work on ports other than
COM1 and COM2.  Does anyone know where I can purchase something like
this.  Looking through the latest issue of PC magazine, all I can find
is serial boards that can be used on COM1 & COM2 or multifunction cards.

Thanks

Just about all serial/serial cards can be configured as COM3 and COM4
as well as COM1 and COM2. Just sure the IRQ's and interrupt
addresses can be configured for your system. Because COM3 and COM4
standards were not defined in the initial IBM PC, many systems
use IRQ lines and interrupt addresses that are not what is commonly
use today.
