I've used GNAT.Serial_Communications on Windows and Linux to transmit
commands to/receive responses from robots via a USB Bluetooth
transceiver.

The package worked as expected for me. I certainly didn't have any
issues with the package blocking on writes. Where is your program
blocking? Is it:

a) right after the Ada statement prior to the Write, but before any
data is transmitted over the serial port

b) mid-transmission (i.e., some of the data is received at the distant
end, but not all of it)

c) after transmitting all data, but before executing the next Ada
statement
