Hi there
if my memory still serves me, 16650 was issued with bug in FIFO handling, so you can easily loose bytes. After some time bug was fixed and now good 16650 are in production. Unfortunately, there is no way to find out chip info, i.e. there is no difference between good 16650 and buggy one. Try to ask Theodore Tso, who is maintaining linux serial drivers. cheers OK On Wed, 23 Apr 1997, Bob Nielsen wrote: > But they are enabled for 16550A, which is the only type you will find > these days. > > Bob > > On Wed, 23 Apr 1997, Steve Hsieh wrote: > > > > > > > I'm certainly interested because I intend to be getting a byte runner > > > 16650 > > > > card and ISDN TA in a about a week. > > > > > > Something to think about before getting a 16650 card...
