fwiw, this change broke my usb->serial adapter i use with my Nokia
DLR-3P cable (i didn't notice earlier since i didn't need to use gprs
for some time).  the chat script just sits there, waiting for a reply
from the phone:

 pppd[564]: pppd 2.4.3 started by salo, uid 1000
 chat[534]: timeout set to 45 seconds
 chat[534]: abort on (BUSY)
 chat[534]: abort on (NO CARRIER)
 chat[534]: abort on (ERROR)
 chat[534]: send (ATE1^M)
 chat[534]: expect (OK)

reverting the revision 1.45 makes it work again:

 pppd[2590]: pppd 2.4.3 started by salo, uid 1000
 chat[1638]: timeout set to 45 seconds
 chat[1638]: abort on (BUSY)
 chat[1638]: abort on (NO CARRIER)
 chat[1638]: abort on (ERROR)
 chat[1638]: send (ATE1^M)
 chat[1638]: expect (OK)
 chat[1638]: <^G8^?^?^?^?`^?^?}ATE1^M^M
 chat[1638]: OK

 chat[1638]: expect (OK)
 chat[1638]: ^M
 chat[1638]: AT+CGDCONT=3D1,"IP","internet.t-mobile.cz"^M^M
 chat[1638]: OK
 chat[1638]:  -- got it=20
 chat[1638]: send (ATD*99***1#^M)
 chat[1638]: expect (CONNECT)
 chat[1638]: ^M
 chat[1638]: ATD*99***1#^M^M
 chat[1638]: CONNECT
 chat[1638]:  -- got it=20
 chat[1638]: send (\d)
 pppd[2590]: Serial connection established.

the adapter in question is:

 uplcom0 at uhub1 port 1
 uplcom0: Prolific Technology PL2303 Serial adapter (ATEN/IOGEAR UC232A), r=
ev 1.10/2.02, addr 2
 ucom0 at uplcom0

i haven't tested the adapter with anything else (e.g., serial console).
