Re2: uplcom(4) problem

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:    Hey Rahul, I got the PL2303 based usb->serial adapters but unfortunately
:    they appear to work perfectly.  I connected up a modem via /dev/ucom0
:    and dialed an ISP using ppp and it works.

    I take it back!

    It turns out that 'ppp' works fine, but 'pppd' cannot seem to read any
    data back from the modem.  When I used pppd to talk to the modem via
    ucom0 it failed to read() data from the modem even though the modem was
    definitely sending data to the computer.  When I used pppd to talk to
    the modem via cuaa0 it read() the data fine (and also hit the continuous
    loop problem).

    So I am able to reproduce *BOTH* issues.
