Kad hoces da ti radi nesto na linuxu prvo pogledaj koji je device id i vendor broj.
Za pci uredjaje je lspci -v a za usb lsusb -v
E sad kako videti uredjaj na srial com portu nisam siguran ali verujem da postoje tools setserial za serial portove.
http://www.icewalkers.com/Linux/Howto/Serial-HOWTO.htmlhttp://www.accesio.com/go.cgi?p=../software/linuxserial.htmlhttp://www.tldp.org/HOWTO/Serial-HOWTO.html`The command setserial -g /dev/ttyS* will list serial devices`
Kad saznas device id i vendor googlaj i mozda nadjes how to za tvoj modem.U svakom slucaju na linkovima gore imas how to za serial modem.
Naprimer:
setserial -g /dev/ttyS*
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3
/dev/ttyS4: No such device or address
/dev/ttyS5: No such device or address
/dev/ttyS6: No such device or address
/dev/ttyS7: No such device or address

setserial -g [-abGv] device1 ...
Available commands: (* = Takes an argument)
(^ = can be preceded by a '^' to turn off the option)
* port set the I/O port
* irq set the interrupt
* uart set UART type (none, 8250, 16450, 16550, 16550A,
16650, 16650V2, 16750, 16850, 16950, 16954)
* baud_base set base baud rate (CLOCK_FREQ / 16)
* divisor set the custom divisor (see spd_custom)
* close_delay set the amount of time (in 1/100 of a
second) that DTR should be kept low
while being closed
* closing_wait set the amount of time (in 1/100 of a
second) that the serial port should wait for
data to be drained while being closed.
^ fourport configure the port as an AST Fourport
autoconfig automatically configure the serial port
^ auto_irq try to determine irq during autoconfiguration
^ skip_test skip UART test during autoconfiguration
^ sak set the break key as the Secure Attention Key
^ session_lockout Lock out callout port across different sessions
^ pgrp_lockout Lock out callout port across different process groups
^ callout_nohup Don't hangup the tty when carrier detect drops
on the callout device
^ split_termios Use separate termios for callout and dailin lines
^ hup_notify Notify a process blocked on opening a dial in line
when a process has finished using a callout
line by returning EAGAIN to the open.
^ low_latency Minimize receive latency at the cost of greater
CPU utilization.
get_multiport Display the multiport configuration
set_multiport Set the multiport configuration
* rx_trigger Set RX trigger level (ESP-only)
* tx_trigger Set TX trigger level (ESP-only)
* flow_off Set hardware flow off level (ESP-only)
* flow_on Set hardware flow on level (ESP-only)
* rx_timeout Set receive timeout (ESP-only)
* dma_channel Set DMA channel (ESP-only)
spd_hi use 56kb instead of 38.4kb
spd_vhi use 115kb instead of 38.4kb
spd_shi use 230kb instead of 38.4kb
spd_warp use 460kb instead of 38.4kb
spd_cust use the custom divisor to set the speed at 38.4kb
(baud rate = baud_base / custom_divisor)
spd_normal use 38.4kb when a buad rate of 38.4kb is selected
Use a leading '0x' for hex numbers.
CAUTION: Using an invalid port can lock up your machine!
U svakom slucaju ovo ti je mozda od neke pomoci, a ako je modem vezan za com1 od 9 pina mali port onda je za sigurno /dev/ttyS0 (0=nula)
Ako tvoj program dajler nemoze da uradi query na ttyS0 onda mozes da napravis /dev/modem link komandom
ln -s /dev/ttyS0 /dev/modem
