Re: emi2: main connection closed by SMSC

[Bruno David Sim�es Rodrigues]

Don't use username is you don't need it.
I'll make a patch soon to use some other command to keepalive. I'll check
a -61 or a -5x like
the one to check message status.

Hi Bruno,

You was looking for a log file with the 31 syntax error.

2001-08-10 12:49:16 [6] DEBUG: emi2 sending packet:
<00/00027/O/31/pass/0539/21>
2001-08-10 12:49:16 [6] DEBUG: Got packet from the main socket
2001-08-10 12:49:16 [6] DEBUG: emi2 parsing packet:
<00/00035/R/31/N/02/Syntax error/F8>
2001-08-10 12:49:16 [6] ERROR: Got negative ack. op:31, trn:0, error:2
(Syntax error), message: Syntax error

I used only username and no password. I do not have one at the SMSC (CMG
EMI), so I guess thats why it fails.

regards

Steffen Lindemann
