Hmm, I'm sorry not having mentioned it before you started to port....
I've already done working ports of telnet and telnetd and have not up-
loaded them because I wanted to do some more tests. :(

But I'll do it today...

[sprintf stuff deleted]

This is due to PTY packet mode, which is not supported by Mint. Look for
ioctl ( , TIOCPKT, ) and the main select loop.

Hmm, do you use HSmodem or some such serial routine replacement (or even
modm0dev)? And what buffers do overflow, the BIOS recv and/or send buffers?

There might be a bug in the circular buffer handling in MintNet, which I
don't believe (SLIP uses nearly the same code), have to look at it.

What seems more likely is a problem with the wakeselect on the BIOS devices.
PPP input uses a deamon to receive and send data from/to the serial port
selecting the devices. What I have noticed is that when using the Mint
builtin drivers with Howards select patches applied then input data comes
in rather largish hunks, ie the wakeup seems not to occur always immediatly
after data has arrived. But I never noticed complete hangs...

Migh this be a bug in checkbttys or is this 'normal', Howard?

I have HSmodem running with 4k receive buffers at 19200.

Well, I usually do an
stty speed 19200 < /dev/ttya
for setting the terminals speed. If you find it better to have only one
program I might add it when I get more time (not until 15th of July).
