Using Linux with H5 Devices

Shell Commands

Testing Serial Ports

To test the serial ports created by the driver, type in a shell:

# cat /dev/ttyACM0 &

# echo –en "ATE0\r" > /dev/ttyACM03

# echo –en "AT\r" > /dev/ttyACM0

Note: Sending ATE0 is required, to avoid issues in the terminal output. It prevents the sending/receiving

spurious characters to/from the modem when used with the Linux commands “echo” and “cat”

You can perform the same test using the other interface (ttyACM1 ttyACM3).

Create a PPP Connection

Most recent Linux distributions have GUI tools for creating PPP connections; the following instructions are for

creating a PPP connection through command line interface.

PPP support must be compiled into the kernel; pppd and chat programs are also required.

pppd needs two scripts: the first script performs the environment setting and calls the second script, which is used

by the chat program. For creating a PPP connection type:

# pppd file /etc/pppd_script &

Example

# Debug info from pppd

debug

#kdebug 4

# Most phones don't reply to LCP echos

lcp-echo-failure 3

lcp-echo-interval 3

# Keep pppd attached to the terminal

# Comment this to get daemon mode pppd

nodetach

# The chat script (be sure to edit that file, too!)

connect "/usr/sbin/chat -v -f /etc/chatscripts/hsdpa_connect"

# Serial Device to which the modem is connected

/dev/ttyACM3

# Serial port line speed

115200

dump

# The phone is not required to authenticate

#noauth
