[erlang-questions] pseudoterminal port process

Not exactly sure what you want to do but ...
have a look at https://github.com/tonyrog/uart, it has got some support for pseduo terminals, 
use "//pty" as the device name in uart:open, and then get the name of the selected slave
device by calling uart:getopts(Uart, [device])

There is an option {ptypkt, boolean()} that can be used to turn on pty packet mode (TIOCPKT)
this is handy for pseudo terminal flow control handling. Because of a little bug, this option
can not be given when opening the device but must be set with uart:setopts (there is a fix on its way)

The problem I have is that the C++ program expects to run under a terminal, and open_port/2 appears to have no pseudoterminal support.  Before I run off and start writing a pseudoterminal wrapper port, is anyone aware of an existing wrapper or some other solution for my problem?

"Installing applications can lead to corruption over time. Applications gradually write over each other's libraries, partial upgrades occur, user and system errors happen, and minute changes may be unnoticeable and difficult to fix"
