Up until now I have had functional AT commands.
I have been attempting to get GSM modem to hook up to the network (for and
unreasonable amount of time), and then all of a sudden, my AT commands started
returning a garbage character right in the middle of my modem responses.
for instance :
sent : 'AT+CFUN=1\r\n'
LONG, STRANGE PAUSE BEFORE RETURN # was formerly nearly instant
ret : 'A\x00T+CFUN=1\r\n\r\nOK\r' # without the trailing \n
there is no PAC0:1 (or whatever it is) returned anymore.
Any thoughts on what might be happening here?
I did change at some point com5 to com4 but it still worked. And then I was
trying to verify the IRQ's so that i could get pppd up and running; still I had
intermittent functionality. It was at some point through this process that the
'mystery character' decided to manifest itself and I have had nothing ever
since.
I have done what I think to be obvious:
rebooted
remade the /dev/ttyS3
setserial /dev/ttyS3 baud_base 9600
Rebooted my desktop in case it was somehow involved
I even reloaded the tslinux-08-24-06.tar.gz from the repository
Reinstalled Python (this is where i issue my AT's)
This method worked up until earlier this morning and now I have spent 8 hrs
trying to figure out what happened. Any input would be greatly appreciated.
