Hi everyone,
I'm trying to get the TS-MODEM2 working with my TS-7800 with no luck.
Short version...
My problem may be as simple as not having the baud rate set properly.
I've tried minicom set to 8N1 at 115200 and 9600 with no luck. I can't
even get the modem's attention (+++). Does anyone know the correct baud
rate settings?
Long version. Here's what I've done so far:
- Set the I/O to ISA mode with the peekpoke 0x555.... commands. This I
know works.
- modprobe ts7800_isa16550 gave:
FATAL: Error inserting ts7800_isa16550
(/lib/modules/2.6.21-ts/kernel/drivers/serial/ts7800_isa16550.ko):
Operation not permitted
So looking through the source for the module, I saw ts7800_isa16550_init
was returning a -1, which I assume was giving the above error. After
changing the return value to 0, the error went away. In total, I
changed these three lines:
Old: static unsigned int io = 0x3e8;
New: static unsigned int io = 0x2e8;
Old: req.irq = 64 + irq;
New: req.irq = irq;
Old: return -1;
New: return 0;
The TS-MODEM2 has jumpers set as follows:
JP1 = off (COMA=COM3, COMB=COM4)
JP4 = on (IRQ6)
Now modprobing again, I look at 'dmesg' and get:
serial8250: ttyS2 at MMIO 0xee0002e8 (irq = 6) is a 16550A
and /proc/tty/driver/serial shows:
0: uart:16550A mmio:0xF1012000 irq:3 tx:1064 rx:0 RTS|CTS|DTR|DSR|CD
1: uart:16550A mmio:0xF1012100 irq:4 tx:0 rx:0 DSR|CD
2: uart:16550A mmio:0xEE0002E8 irq:6 tx:0 rx:0 CTS|DSR
Yeah! So it's /dev/ttyS2.
Unfortunately, I still cannot get the modem's attention. Does anyone
have the piece I'm missing?
Thanks,
-Frank
