I have used Gambas serial port for 12 years now without problems. If there is nothing in the serial port queue, then that line might block.
I use this: . . . L=Lof(Sport) 'how much is there now? if L>1 then L=L-1 'leave at least one byte for next time around. if L>0 then Read #Sport, Rx, L 'get all less one byte Rx_all = Rx_all + Rx 'combine this piece into the whole receive string. Rx="" 'just in case it loops around, don't re-read Rx. . . . Most importantly, please do not think that just one READ will retrieve a whole line or chunk of data from your serial port. It will get only part of it because your computer reads bytes much faster and empties the receiver buffer much faster than data send over RS232. -Fernando -- Open WebMail Project (http://openwebmail.org) ---------- Original Message ----------- From: alexchernoff <alexchern...@hotmail.com> To: gambas-user@lists.sourceforge.net Sent: Mon, 8 May 2017 22:45:11 -0700 (MST) Subject: Re: [Gambas-user] Serial I/O with byte data > Thanks Mike, > > what I have is pretty much the same, it's this line that causes everything > to stop. > > *Read #Sport, Rx, Lof(Sport) * > > A very similar program written in Xojo on the same system using same serial > port works just fine.
