#Coolterm debian serial#

if me.Caption = “Disconnect” then 'Disconnect from the serial port A keen eye will see that most of this is taken from Xojo’s own serial example… I’ve tried different desktop computers and laptops as well.īelow is the code snippet I’ve used when pressing a “connect” button on the GUI. I’ve tried my running my app in Xojo version 2015r2.2 up to 2016r4.1 with the same result. I don’t believe its a USB to serial converter issue as FTDI is well known and supported, other brands also work at the required speed (with different software) and I’ve tried a few different other converters from various sources.

I don’t believe its a Linux driver issue due to the fact that other programs have no issue opening the port/device at 921600Bps. Like I said above, My app and CoolTerm have no problems in windows. It too is fixed by opening and closing the port with a different program then running CoolTerm again. The fine program called CoolTerm written by Roger Meier in Xojo has the same issue. Setting DataTerminalReady to TRUE has fixed this problem but not the baud rate issue.īut this problem doesn’t seem to be related to just my app. This was found after extensive searching for decent serial control line monitors (ended up using statserial) to see if anything bazaar was happening. What I did find was Xojo was setting DTR to false on serial port opening. The interesting thing is if open the com port at 921600Bps and close it again using a different program or three (moserial, cutecom and gtkterm) then go back to my app, it will work fine at 921600Bps. What I found is the port is opened at the default computer start up rate of 9600Bps and transmitting the data at this rate… This was tested with a logic analyser on the data lines of a Prolific USB to serial chip… Problem seems to be the opening of the port at 921600Bps… It doesn’t seem to happen… My app works fine in Windoze XP up to Win 10 on any computer I can throw at it. This was successful and worked well but since discovering Xojo I’ve wanted my own version to work cross platform… Once again I re-wrote my version but in Xojo this time.

There is a commercial app thats written for Windoze that works well but I’d like to use the device in Linux, So I wrote my own version in Linux software called Gambas. I have a black box device (eprom emulator) that communicates via a FTDI USB to serial chip (virtual serial port) at 921600Bps. Hi all, I think the title should address my question but here goes…
