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.
