As I mentioned above I have tested with every different mode the BIOS has.
I have also made a cable w/ a little less than 1mt length to verify if the
problem was in length. The first cable I used had 1.80mt but works
perfectly with computer #3 (refer to original message)

As I wrote in the original message is that it seems that using kernel
driver like this:
insmod parport
insmod parport_pc io=0x378 irq=7 dma=3
insmod baycom_epp iobase=0x378 mode="extclk intmodem extstat divider=16"
ifconfig ... up
The EPPFlex doesn't seem to be in 76800 speed because it doesn't react
to the other modem packets.
Check out the original message about this subject.
