Update: Don't think it's the adapters. Minicom doesn't exhibit this
behavior on a different computer with a USB card (the computer I'm
working with is an HP laptop).
Using a PCMCIA USB host card on my laptop seems to fix the problem
there, also.
So, I don't have a "missing first character" problem anymore as long as
I use the PCMCIA USB host on the laptop.

Hello,
Don't know if this is an unusual problem or not...
I'm running RedHad Fedora Core 2, and using either a Belkin USB-Serial
adapter F5U109 (driver mct_u232), or a Dynex DX-UBDB9 adapter (driver
pl2303).
The problem is that the first incoming (received) character is dropped
when a program is started. After that, it seems to work fine.
When minicom is started, for instance, the first incoming character is
dropped; on both adapters. I've written code to initialize /dev/ttyUSBx,
and it does the same thing.
Of course, on a pc with a real serial port, none of this happens.
Has anyone seen this?
Thanks,
Bob Wirka
