Overview
The TS-Iridium provides a UART connection over PC104.
Full Iridium Documentation
To receive the full documentation for this board you must contact your satellite service provider. This documentation is only intended to get the UART connection established.
Configuration
You must alter IRQ and the IO address to reflect your pin configuration.
TS-72XX
This series will automatically detect the COM port and create it with /dev/tts/<COM number>. The COM number will depend on your pin configuration.
TS-7800
This example is from Debian:
. /initrd/ts7800.subr
pc104on
modprobe ts7800_isa16550 irq=7 io=0x3F8
To view if it loaded correctly, run 'dmesg' and you should find a line similar to this:
serial8250: ttyS2 at MMIO 0xee0003f8 (irq = 71) is a 16550A
So in this case the COM device will be /dev/ttyS2.
Testing the Iridium
To test communication, you can use picocom or any similar serial control application. Connect at 19200 8n1 with no flowcontrol and send an "AT". The modem should echo back "OK". Replace the tty device with the corrected location for your device.
root@ts7800:# picocom /dev/ttyS2 -b 19200
picocom v1.4
port is : /dev/ttyS2
flowcontrol : none
baudrate is : 19200

Iridium Power
With JP5 enabled, the Iridium modem will receive power by default. With either configuration of that jumper you can always toggle the power from the PLD. The modem typically takes 750ms to power on, and can take up to 3s to turn off.
