Thanks for the response, cat /dev/ttyUSB0 produces nothing
Today I found more information and did the following
I tried setting the port using stty -F /dev/ttyS1 speed 4800 raw cs8, as I found a web page where a fellow was monitoring a serial port with a the nema gps devices use this setting.
stty -a -F /dev/ttyUSB0 =
speed 4800 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>;
start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

I then followed again with cat < /dev/ttyUSB0 >| nema_cmd_version_response.txt and got an empty file. I am unable to get anything from the gps
It appears, according to the sourceforge web site I need to send a command to the gps for it to start sending data - on sourceforge a fellow uses another port and special hookup to send the commands to the gps so he can monitor the output. (http://nst.sourceforge.net/nst/docs/user/ch11s02.html
) I don't have these additional hookups.
I tried running gpsd and using telnet to send commands through gpsd to get some type of respone, but nothing, and nothing going to the cat /dev/ttyUSB0 either during this time.
