Re: Q68 serial buffers

I tried SER_BUFF 1,80,80, SER_BUFF 80,80 and SER_BUFF 80. But I just discovered that all SER_xxxx commands give a 'not found' error. Looks like they cannot find the driver's linkage block somehow. Found the bug. All the SER_* commands set the parameters through a Thing called 'ser_par_prt'. However...

Re: Q68 serial buffers

It's important to distinguish mass storage driver issues and SER. The SMSQ/E mass storage driver can get painfully slow during write, and blocks everything else. This affects ethernet as well - software buffers can't help reliably because no interrupts are handled meanwhile. Trying with Ramdisk ins...

Re: Q68 serial buffers

what is the exact SER_BUFF command you are using? As the Q68 has only one single port it might or might not be needed to specify the port number (which is different to most other SMSQ/E platforms) I tried SER_BUFF 1,80,80, SER_BUFF 80,80 and SER_BUFF 80. But I just discovered that all SER_xxxx comm...

Re: Q68 serial buffers

Message sent to the QL-Users list. Of course I could find out by delving into SMSQ/E's source code. But the SER_BUFF command probably needs fixing. Meanwhile, I'll look at Minerva to see if a backport is possible. This will require a modification to its int2 handler since the Q68 treats the external...

Q68 serial buffers

I've been doing some tests with the Q68's serial port. It's well known that it doesn't support flow control. So this means that if you receive data at, say, 38400 bps or higher, you need a buffer large enough to hold all the incoming data to give the Q68 a chance to digest it (for example to write a...

Re: Announcing availability of a QLNET driver for the Q68 (ND-Q68)

Thanks Martyn! Unfortunately I haven't been able to test it up to now but it will be a nice project for my upcoming vacation :) . This driver could also be incorporated into the Q68 Minerva image (in the extrarom space), as well as a serial driver. One idea for the hardware geeks: why not use the so...

Re: Link ASM and C code

Hi, I have a main programme in assembly, and I wish to add some functions with integer arithmetics, easier coded in C possibly (or Pascal). I use mainly `GST Assembler' (first prog I had on my QL) and just started looking into `GST C'. Assembly has now some unresolved labels, thats where the `C' fu...

Re: Help, connecting QL to BBS

I used Maximus on DOS (later OS/2) until 2003, it had Telnet access via Vmodem on one line (the other two or three lines dedicated to analogue modem and ISDN). I still have the files and even managed to put it back online again a few years ago using NetFoss under Windows. Unfortunately I got only a ...

Re: Help, connecting QL to BBS

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 ...
