tFTP syntax for Telnet saving Actiontec config.

I'm looking for the correct tFTP syntax for Telnet saving Actiontec
config.

I'm trying to save the setup configuration in a Qwest Actiontec
GT701-wg. (This is the same as used by such as Verizon, and similar to
the GT704, which has 4 Ethernet rather than the one of the GT701.)

Using the tips at
"3.2 Saving the configuration (Windows)" in "ActiontecGT701" at

http://www.seattlewireless.net/index...sPointHardware

(among others)
I got as far as
8) in Telnet: tftp -l config.xxx -p

Apparently, I do not have the correct syntax.
I found "tftp commands vary across different implementations"
[Section 4.1, http://wiki.openwrt.org/OpenWrtDocs/Installing , and
others]

I'm using Win98 on Ethernet to the GT701.
Browsing to 192.168.0.1 accesses the GT701 user interface okay.
For Telnet, I have Tera Term Pro 2.3 (T. Teranishi, 10 Mar. '98) and
Tera Term Pro Web 3.1.3 (T. Teranishi and Ayera.com, 07 Oct. '02)
For tFTP I have Tftpd32 v.2.80 Build Jan. 14 '05 (Philippe Jounin)
I don't know where to find all the values for setting up tFTP.
For "server interface" I'm using the assigned IP address (192.168.0.9)
for the client where I'm working.
For Tftp Client tab, "Host" I'm using the 192.168.0.1, Port 23, the
same as Telnet uses successfully.
For File, I tried the "-l config.xxx -p" (without the quotes).
At the Telnet prompt, I also tried
tftp -l config.xxx -p
Telnet replies "unable to write" (I neglected to copy the exact
message).

Any leads to answers would be appreciated.
TIA

I have two Actiontec GT701-wg for which there is almost no
documentation how they've been set up, and one is working verrry
slowly; I want to save the configurations before further repair. (The
other was working fine until it was relocated. That one powers up and
lights go green okay, but it allows no access. The problem is likely
syntax. I have the passwords, probably ; )` From viewing the default
config.xml, it appears that comparing the installed config of the two
might isolate problems.

Both devices appear to be fine otherwise.
