From: bairds@penchiss10.ee.pdx.edu (Scarrow) Subject: STB Multiport serial woes ... Date: 1 Oct 1993 12:53:21 -0700
Having read this and that, I decided to go ahead with a purchase of the STB
four port serial card (sort of an AST fourport clone). Well, after having
finally navigated the difficulties (we had to purchase 9-pin to 25-pin
converters to attach our modems ... and of course they screwed up the gender
the first time) it seems that it is ignoring incoming data. To explain, if
I send, for example, ATZ, I see the modem flash both send and receive (as it
echoes the ATZ and then sends the OK). So the modem is functioning properly
and is sending the responses back, but I never see these responses on the
screen under kermit. I checked the cables out themselves and, according to
the docs I have, all the pins matched up just fine. (Then again, the docs
came from the people who made the cables ... *wink*) Anyway, I have some
small suspicion that, because I have no idea what the hell I'm doing, it might
be something in the software end. I'm running SLS 1.03 currently (0.99pl12
theoretically) and setserial 2.02. My rc.serial looks something like this
for the four ports:
/etc/setserial /dev/cua4 uart 16550A irq 15 port 0x1f8
/etc/setserial /dev/cua5 uart 16550A irq 15 port 0x1e8
/etc/setserial /dev/cua6 uart 16550A irq 15 port 0x2a8
/etc/setserial /dev/cua7 uart 16550A irq 15 port 0x1a8
Obviously, at least some of this is working, as transmitted characters go
through okay. I used mknod to make nodes for cua4-cua7 and ttyS4-ttyS7, by
simply incrementing minor device numbers (I actually made nodes for cua2-cua7
and ttyS2-ttyS7), since they didn't exist previously. Any comments, etc.,
would be extremely welcome. :)
