P.S. - Here's how I send a command to the device after the
"myDeviceNames" function tells me which devices are available:
global gCurrentDevice
on mouseUp
-- locate the device driver
put myDeviceNames() into tDevice
filter tDevice with "usbmodem*"
if tDevice = empty then
answer "Can't find device."
exit to top
end if
if the number of lines in tDevice > 1 then
answer "Multiple device drivers!" & cr & tDevice
exit to top
end if
put (item 3 of tDevice) into gCurrentDevice
open driver gCurrentDevice for update
put the result into fld "result"
write tMyCommand & cr to driver gCurrentDevice -- be sure the CR is
there!
put the result into fld "result"
end mouseUp

Hey Peter,
Is your device listed in the output of this function? If so, try
opening it and writing a command to it.
function myDeviceNames
# Handler courtesy of Ken Ray & Dar Scott
local theNames="", ioregOutput, skipLines, temp
local IOTTYDevice, IODialinDevice, IOCalloutDevice
set the hideConsoleWindows to true
put shell("ioreg -n IOSerialBSDClient") into ioregOutput
repeat forever
put lineOffset("IOSerialBSDCLient",ioregOutput) into skipLines
if skipLines is zero then return thenames
delete line 1 to skipLines of ioregOutput
-- Get all the data between the braces
put char(offset("{",ioregOutput)) to (offset("}",ioregOutput)) of
ioregOutput into temp
get matchText(temp,"\"IOTTYDevice\" = \"(.*?)\"",IOTTYDevice)
if it is not true then next repeat
get matchText(temp,"\"IODialinDevice\" = \"(.*?)\"",IODialinDevice)
if it is not true then next repeat
get matchText(temp,"\"IOCalloutDevice\" = \"(.*?)\"",IOCalloutDevice)
if it is not true then next repeat
put IOTTYDevice,IODialinDevice,IOCalloutDevice & lineFeed after
theNames
end repeat
end myDeviceNames

Thanks everyone! Its Linux, the OS that is being used.
Sarah's article is interesting, but my problem is that the device is
USB. So a serial to USB adaptor won't do it - it will allow use of a
serial
device on a usb port. If anything what I'd need would go the other
way -
allow use of a usb device on a serial port.
One other suggestion is to make one of the usb ports into a virtual
serial
port. Yes, maybe. Again, not something I've ever gone near, but will
probably try it before this is over! Apparently you can map them...
