putc to a clist with no reserved cblocks

I haven't moved up to 5.4-PRERELEASE yet but have had this problem 
since using UC232 adapters w/ 5-stable.  Adding this line to 
uplcom.c seems to help with the read() hang problem:

#define RSAQ_STATUS_CTS	0x80

but I still get a lot of "putc to a clist with no reserved cblocks" 
whenever mgetty restarts coming out of ppp mode.

I heard that it's been fixed on -current; wonder when it'll get to
