Haicom HI-204E GPS Receiver

Problems with SERIAL and FOPEN commands

By Ross - usenet poster


Hi all,

I've got a problem trying to acquire data from a GPS receiver.
I have a Haicom HI-204E GPS receiver, which I connect to my pc via USB. The
GPS driver emulates a COM port, infact when the receiver is connected a COM
4 port appears in the control pannel of Windows XP.

Problems starts when I try to acquire data. I do the line:

gps = serial('COM4','BAUD',4800,'Dat­aBits',8,'StopBits',1)

and when I do

fopen(gps)

Matlab (I use R13) goes in busy mode and never goes out.

Can anyone explain me why it doesn't work?
Thanx in advance, bye.

Well, the problem seems to involve only the release 13 of Matlab.
I've done the same commands in the R14 and it works so well.
Thanks for reply, bye

Are the parameters you set the ones specified by the instr. maker and
have you also set flow control, parity and the terminator character.
