The Sinclair QL Forum

The QL serial port also can't generate a BREAK signal (set the TX line high for a certain length of time). I had to simulate this in my terminal emulator by setting the baud rate to the lowest and then send 64 NULs and hope that the system it's connected to mistake this to being this signal.

There is a way to set the TX line directly. Take SV.TMODE, clear bit 4, set bit 3 to 0 for ser1 or 1 for ser2 and set bit 7. Then write this to PC.TCTRL ($18002). You probably should disable interrupts for the duration of the break signal.

I will talk to Bo (who wrote the firmware) and see about getting this accounted for in the firmware by adding a new command.

Bo suggests....

ATF4 turns off all flow control
AT&W saves that status, so it is the default.

Could you give that a try and report back?

Hi,
I experienced the same problem with BBQl....

ATS54=2 (DTR always High) solved the problem

Yes, I am using a BBQL (SuperGoldCard + QL-SD + Hermes). I haven't tested Ser1H because I don't have the right cable, my serial cable is adapted to ser2. (That serial cable does not work on ser1.) Could that be the problem?

About serial lead, for Ser1, would this be the right cable? https://www.sellmyretro.com/offer/detai ... -Lead-4186 …. And for Q68, what would be the correct cable? (I think a null modem cable does not work in this case).

bixio60, what WiFi module do you have. Does it run Bo's firmware?

Bo replied:

ATS54=2
AT&W (this saves the config and makes it the default behavior)

So, the default is RTS/CTS, so it would make sense that they would have trouble
if they didn't build compliant hardware.

The command should work for them fine. The algorithm for going to stream mode is
something like this: If you specify flow control settings using the 'D'ial
command (ATDXT for example), then they will be respected. If you don't specify
anything (just ATDT), and command mode is using rts/cts, then stream mode will
also use rts/cts. Otherwise, if you don't specify anything and command mode is
using XON/XOFF or Nothing, then stream mode will not do any flow control.

OK, now everything works correctly !!! ... Thank you bixio60!!

Good!


PD:
I like QLTerm, it is very useful and simple to use. (Jan, Great!).

What a hassle to actually

End up on an Amstrad BBS

(just joking)

Congrats you got it running.

Hi,

There a list of connectable of Internet BBS shown at:

https://www.telnetbbsguide.com/bbs/list/detail/

My BBS ran on a QL with Qbox or Pbox as the BBS software. I thought that the BBS system had died and most SYSOPs (BBS Owners), had moved to web based systems.

Which begs the question, should I get my BBS up and running again or convert it to a web site?

I want the BBS running on a QL based system, so some sort of serial connection to am internet aware computer. Maybe a Raspbery PI and use TCPSER, see this link
