Comunicating through COM ports

[David Mallwitz]

Comunicating through COM portsChapter 19 of Mark Hammond and Andy Robinson's
'Python Programmingon on Win32' covers this quit well, and with the
Activestate Python distro there is a multithreaded demo called
'win32comport_demo.py'. But here's what I do - example is from a console
connection to an old Cisco router.

>>> from Serial import Serial
>>> ### open the COM1 port
>>> serialconfig = Serial.PortDict()
>>> serialconfig['port'] = Serial.COM1
>>> serialconfig['rxBufSize'] = 4096
>>> port = Serial.Port(serialconfig)
>>> port.open()
>>> port.write('show conf \r')
>>> x = port.read()
>>> x
'show conf \r\nUsing 768 out of 32762 bytes\r\n!\r\nversion 11.1\r\nno
service u
dp-small-servers\r\nno service tcp-small-servers\r\n!\r\nhostname

Anybody could give me an example code of how connect/comunicate through COM
ports (i.e. COM1, COM2). I'm under windows 98.
Thanks!!!
