            Bug ID: 38690
           Summary: corrupted serial communications
           Product: Wine
           Version: 1.7.38
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org

      Distribution: ---

Serial communications are corrupted/laggy/ugly.  Tested on a Dell Latitude D630
running Linux Mint 17.1 and Wine 1.7.38 from WineHQ PPA, as well as Wine 1.6.2
on the same hardware from the Ubuntu repo.  The issue occurs whether it's the
hardware 16550 serial port or a USB attached one.  (In this Linux system case
the USB adapter was Prolific-based.)

I observed the same symptoms on Mac OS X Mavericks, compiling Wine 1.7.43 via
Macports, using an FTDI-based USB adapter.

The primary test scenario included Tera Term 4.87 talking to a Cisco router's
console port at 9600 N,8,1 without flow control.  Data back from the Cisco was
incomplete, latent and just generally ugly.  Using the same hardware and
minicom running natively in either Linux or OS X there were no issues.

Tera Term to a router provided the cleanest environment in which to observe
what was happening.  I can't get serial communications to work properly
regardless of the Windows app or the serially-connected device.
