Recently I asked the net for the instructions on adding extra ports to a xenix system. I have used the instructions produced by Coert Vonk and I am still having difficulties. The new com3: port works fine but I have lost com2: The hwconfig utility shows: name=serial base=0x3F8 offset=0x7 vec=04 dma=- unit=0 type=Standard nports=1 name=serial base=0x3E8 offset=0x7 vec=05 dma=- unit=2 type=Standard nports=1 My master and sioconf.c files are exactly as per the instructions. The hardware is a Unisys PW2 800/25 with two built-in serial ports and an additional ventel internal modem. It is the second buil-in port which is not now working. How does the unit number work into all this? Is there something else I need to do? BTW Coert's instructions are missing one piece of information: how to create the nodes and what minor numbers they should be given. There is one way in which the modem is not working entirely satifactorily: it will not answer at 2400 baud I alsways get connect 1200 at the other end This is probably insanity on my part (!) Any ideas? Thanks in advance to anyone who can assist me with this. Dick Hacking
