Subject: access to RS-232 signals from user-space?
Date: Wed, 26 Mar 2003 12:41:04 -0800 [thread overview]
Message-ID: <1048711267.1460.9.camel@amit.metricsystems.com> (raw)
Hi all,
I have successfully run a SLIP link between two machines over their
serial ports. We now want to replace the null-modem cable with a radio
at each end connected to the serial port. We also want the ability to
"drive" the radio i.e. use flow-control based on the modem signals on
the radio.
Can anyone enlighten me about the facilities offered by the kernel to
control the various RS-232 lines from kernel-space or user-space? Any
pointers would be helpful.
Regards,
Amit
