Mscomm with IR-modem

[Oscar Lindahl]

I'm trying to connect a pc with IR-port to a DI27 IR
modem connected to a Ericsson T18.
I can send "AT" but i receive AT||OK||
("|" means something strange, guessing carriage return
or something)
Problem is I'm also receiving what I'm sending out.
When I connect direct to COM4 with Hyperterminal I can
send "AT" and receive a clean "OK" on the next line.
I'm guessing that some controlflow is wrong.
This will be a problem later since I'm planning on reding
out the telephonebook and deit it..
Anybody knows how mscomm should be setup?
Really needs help since I cant find any info anywhere.

Hi,

I work very often with MSCOMM controls and I think that the Explanation for the AT is that your Echo is ON.

The 2 bars are &h0A and &h0D the "Carriage Return" and "Line Feed" caracters. Hyperterminal automatically processes the ENTERs and you see each of your commands one under the other.

You should disable the ECHO, the typical command is ATE0 and I would also suggest that you disable all flow control and compression on the modem in the init-string you send him...

Hope I helped..
